PHP Form Validation: Radio Buttons

Hey everyone -
I'm trying to do two things here with an addition to one of
my forms using
PHP.
1. Attempting to validate if one of the radio buttons has
been selected.
2. Displaying which radio button is selected once the page is
reloaded
(checking for validation errors). That is - if they've
selected a radio
button but didn't fill in the other area - I want the radio
button they've
already selected to be actually "selected" once the page
reloads.
Here is the series of radio buttons:
<input type="radio" name="subject" id="subject1" value="1"
/>
<label for="subject1" class="labelbold">I wish to
contact you regarding
website design</label><br />
<input type="radio" name="subject" id="subject2" value="2"
/>
<label for="subject2" class="labelbold">I wish to
report a technical
error</label><br />
<input type="radio" name="subject" id="subject3" value="3"
/>
<label for="subject3" class="labelbold">I wish to
report an error with the
copy</label><br />
<input type="radio" name="subject" id="subject4" value="4"
/>
<label for="subject4"
class="labelbold">Other</label><br />
This is how I'm validating my checkboxes:
if($_POST['confirmbox'] == false) $error[] = "Check the
Privacy Policy
Agreement Box";
However, using "false" doesn't seem to matter with the radio
buttons. So,
how can I get the radio buttons to validate that ONE was
selected and how
can I show that selected button on a page reload (I'm
thinking I may need to
dynamically generate the value=""....<?php...?>....?).
Thanks!

Hello there -
After no replies - I decided to strain my brain (ha-ha) - and
finally
figured out the solution to the problem.
For the curious - I added this to each <input...>
field:
<?php if($_POST['subject'] == "1") echo'
checked="checked"';?>
And then for each <input...> I changed the "1" to the
corresponding value
each field was given.
Have a wonderful night. :)

  • PHP Form Validation and Radio Group

    Hi David,
    I'm trying to set the initial state of a radio group to none.
    Please look at the file http://ecopethandbags.com/contact.php. The initial state is set to "No"
    In Dreamweaver, I've set the initial state to "Unchecked"
    I don't understand the code for the radio buttons in my file (see attachment).
    What I am trying to do is to have the radio group initially unchecked but required.
    I have 2 questions:
    1) - How can I control the initial status of the radio group when I use the PHP form validation?
    2) - How can I set the validation so, when one of the radio buttons is not checked by the user, a warning flag like "Please make a choice" comes up.
    Thank you much!

    Just change the following section of code:
    <?php
    if (!$_POST || isset($missing) && $_POST['subscribe'] == 'n') {
      echo 'checked="checked"';
    } ?>
    Remove the !$_POST || like this:
    <?php
    if (isset($missing) && $_POST['subscribe'] == 'n') {
      echo 'checked="checked"';
    } ?>
    The checked="checked" will be inserted into the code only if the form has been submitted, but neither radio button has been selected.

  • I want to build a form with radio buttons to limited clients ticking every option.

    I want to build a form with radio buttons to limited clients ticking every option. I have a range of products and in order to quote accurately I want to get specific information.

    If I get this , you want to show form options to specific clients not to all site viewers ?
    You would need to create a secure zone for this where permitted viewers can login and view the form with all options , in form itself we cannot setup this as few customers will view other options and others will view a different one.
    This can be done from your hosting end. Or if you are using Adobe server for hosting then you can create some profiles for customers and then setup a separate form altogether to achieve this.
    Thanks,

  • PHP Form Validation and Insert Records

    Hi There,
    I've been scratching my head for 2 days and couldn't find a solution.
    Here is my problem:
    Go to http://ecopethandbags.com/contactTest.php and click the "Send Comments" button.
    You will see that the validation works.
    Now, go to http://ecopethandbags.com/contactTestInsert.php, this time, I've inserted the "Insert Record" server behavior.
    Click the "Send Comments" button again.
    You will see the ugly message like "Column 'firstname' cannot be null" in a plain white page.
    My question is:
    How can I insert the PHP form records in my database and take advantage of the form validation nicely like in http://ecopethandbags.com/contactTest.php
    I am attaching the files.
    Thank you for you help!

    Use simple PHP logic to merge the scripts together.
    Dreamweaver automatically puts the Insert Record server behavior code at the top of the script. You need to adapt it so that the validation is done first. If the validation succeeds, use the Insert Record server behavior. If not, redisplay the form.
    if (array_key_exists('send', $_POST)) {
      // validate the form input
      if (!$suspect && empty($missing)) {
      // send the mail
        if ($mailSent) {
        unset($missing);
        // insert the Insert Record server behavior code here

  • Email form using radio buttons

    Hello! I hope someone can help me out with this one!! I will
    start off by saying that I don't know too much about action script,
    but i have created a Flash email form with just text fields that
    has worked. Now I need to create a form with three sets of radio
    button groups. I need to pass the variables to a php email script.
    Can anyone guide me through this?

    THanks for you help Rob, but I still can't get it to work
    correctly. I'm not getting any email at all. I have a radio button
    group set up. The groupName is "Group1". Then there is a results
    text area on the screen with a var name of "results_ta". My email
    text area's var = "email_ti". I have a submit button component on
    the screen as well. The instance name is "submit_button". Below is
    the flash code that is on the first frame of my movie:
    var submitListener:Object = new Object();
    submitListener.click = function(evt:Object) {
    var result_lv:LoadVars = new LoadVars();
    result_lv.onLoad = function(success:Boolean) {
    if (success) {
    result_ta.text = result_lv.welcomeMessage;
    } else {
    result_ta.text = "Error connecting to server.";
    var send_lv:LoadVars = new LoadVars();
    send_lv.email = email_ti.text;
    send_lv.radioOne = group1.selection.data;
    send_lv.sendAndLoad("sendmail.php", result_lv, "POST");
    //send_lv.sendAndLoad("sendmail.php", "POST");
    submit_button.addEventListener("click", submitListener);
    stop();
    Next my php code is as follows:
    <?php
    $sendTo = "[email protected]";
    $subject = "My Flash site reply";
    $headers = "From: " . $_POST["email"] ."\r\n";
    $headers .= "Reply-To: " . $_POST["email"] . "\r\n";
    $headers .= "Return-path: " . $_POST["email"];
    $message = $_POST["radioOne"];
    mail($sendTo, $from, $subject, $message, $headers);
    ?>
    Do you see anything that is off? I think I've lost it,
    because I had an email being sent, it just didn't add any of the
    info, but now I'm not even getting an email sent!! I'm in despair
    because the project is due tomorrow!!!
    thanks!

  • Pre-populating forms with radio button values

    I have been pulling my hair out trying to figure out why my action page is not being pre-populate with the value that is passed from the radio button selection.

    Thanks for your reply.  The radio button was placed inside the anchor so that when the user selects that employee, it will pre-populate the from base upon the "Action" selected (i.e. Edit Employee and Delete Employee).  I quite sure this can be done with out using javascript.  I know that I accomplish this by using a drop-down list, but I would like to use the radio buttons instead because I would have to change my code.
    Here is the  code with the radio button:
    <tr bgcolor=#backgroundcolor#>
    <td><input type ="radio" name="EmployeeID" value="#employees.EmployeeID#"</td>
    <td><a href="http://localhost:8500/spiderbytes/assignments/employee_details.cfm?EmployeeID=#EmployeeID#"> #employees.FirstName# #employees.LastName#</td>
    <td>#employees.Title#</td>
                    <td>#employees.DepartmentName#</td>
    <td>#employees.PhoneExtension#</td>
                        <td>#employees.EmailAddress#</td>
    </tr>
    Here is are some ways that I coded my form action is coded:
    <form action="admin3.cfm" method="post">  OR

  • Creating a form with radio buttons that users can fill, save, and e-mail back

    Hi all,
    I am new here, so please forgive me if this answer has already been answered. I have been looking around and still have not been able to find an answer.
    I have created a pdf in InDesign and opened it in Acrobat to create a form out of that existing PDF. The form needs to contain radio buttons and text fields. When I save it to test it out on Adobe Reader (for the typical user), it says that I am only allowed to save it in its original form (without any of the changes) thereby making this form useless (I do not want users to print it out; I'd like them to email the entire PDF back to me).
    I've looked online and found some answers saying that I would just need to enable commenting, but when I tried that, I could no longer select any of the radio buttons in Adobe Reader.
    Any suggestions?
    Thanks in advance.
    I'm on a Mac using Adobe Acrobat 7 Professional.

    You won't see that in 7. It didn't exist until Acrobat 8. Though It would work with PDF's opened by Reader 7.
    The only choice you have is connacting someone at Adob coporate and finding out how to sign up to a Service they have that will llow you to do that.
    Caution: its very, very expensive and unless  your fortune 1000 company you can't afford it.
    OR you could upgrade to Acrobat 10 (if you have a Machine capable of running it - Intel Only) or Acrobat 9 (PPC and INTEL).
    Note the feature they speak of only allows for 500 instances of any one PDF set up to do so.

    hi phoenix!
    ok, let's see...
    your "thank you" page is cfincluded in the "sendmail" page,
    so it will
    have all the passed form vars available to it, which means
    you do not
    have to store the radio button selection in the session scope
    or
    anywhere else...
    i think a cfswitch/cfcase construct to check for selected
    radio button
    will serve you better than lots of cfif/cfelseif/cfelse...
    as for preventing submission of page2 without selecting a
    radio button
    first:
    a) pre-select one
    b) use client-side javascript to make sure one is selected
    (use an
    onsubmit event in the form tag or onclick event in the button
    - you will
    have to change the button type from submit to button, and
    change its
    name from submit to something else - there are possible
    issues with
    having a button named submit in your form if you are
    suibmitting the
    form through js...
    c) you could also use server-side cfml to check that a radio
    button is
    selected but it requires a lot of extra code and changes to
    your
    forms/pages...

  • Help with validating radio buttons

    I would like to set my radio button so they can only click it after they have entered text into the 2 previous text fields.  Can someone help me out with a script how to do that?
    Thanks

    Please try the following Script :
    // Function to enable form fields function
    EnableFormField (cFieldName) {
    // First acquire the field to be enabled
    var oFld = this.getField(cFieldName)
    // Next acquire the hidden field with the normal colors
    var oNmlFld = this.getField("NormalColorsFld");
    if(oFld) {
    // Make field interactive
    oFld.readonly = false;
    // Restore Normal Colors
    oFld.fillColor = oNmlFld.fillColor; oFld.borderColor = oNmlFld.borderColor; oFld.textColor = oNmlFld.textColor;
    // Function to disable form fields function
    DisableFormField(cFieldName) {
    // First acquire the field to be disabled
    var oFld = this.getField(cFieldName)
    if(oFld) {
    // Make field Read-Only
    oFld.readonly = true;
    // Set Grayed out colors
    oFld.fillColor = ["G", 0.75]; oFld.borderColor = ["G", 2/3]; oFld.textColor = ["G", 0.5];

  • Fillable forms with radio buttons (Using Adobe Reader X)

    I have two questions: First question, I have a fillable form with "yes" and "no" radio buttons. Currently the radio defaults to answer "yes", but I would like both the "yes" and "no" fields to be empty, which would allow the user to select an answer on his or her own.  Second question, is there a way to make an answer required before moving on to the next question?
    (Using Adobe Reader X)
    Message was edited by: mp2athome

    You need to check and make sure that the options  for each radio button do not have the "Button is checked by default" selected.
    You can make all the following answer radio buttons "read only" and only after one of the choices for the preceding question has been answered are the radio buttons for the next question are write enabled.
    You will need Acrobat to create the form.

  • Please help! How can I validate Radio Buttons and List Menu with PHP.

    Hello everyone, I have been learning PHP step by step and
    making little projects.
    The point is I find it easy to learn by doing "practical
    projects."
    I have been reading the David Powers's Book on PHP Solutions
    and it's really great, however there is nothing mentioned regarding
    Validating Radio buttons. I know the book cannot cover every aspect
    of PHP and maybe someone in here can help.
    I have been learning how to process HTML forms with PHP.
    The problem is every book or tutorial I have read or
    encountered fall short on validation.
    I'm wondering how I can learn to validate Radio Buttons and
    Select List Menu.
    I have managed to create validation for all other fields but
    have no clue as to how I can get validation for Radio Buttons and
    List Menu.
    I would also like an error message echoed when the user does
    not click a button or make a selection and try to submit the form.
    I would appreciate any help.
    Patrick

    It's not that default value is "None." In fact it's not. It
    will only be
    "none" when the form is submitted.
    Also if your submit button is names 'send' then
    $_POST['send'] will only be
    set if the form was submitted.
    Make sure you didn't hit the refresh button on your browser
    which usually
    reposts the information. Also make sure you did not reach the
    form from
    another form with the same button names.
    Otherwise paste the snippet.
    Also you can check what fields are set in the post array by
    adding this to
    the top of (or anywhere on) your page:
    print_r($_POST);

  • Adding a radio button to a popup

    Hi all
    I have a command button when clicked on it a popup should come and it should display all the Digital certificate names stored in the system in the form of radio button along with certificate names.
    Presently when clicked on command button, the button calls a method in AMIMPL which returns the name of the certificate.
    Now my requirement is a pop should be invoked (This is already done using invoke POPUP method )and the certificate name should be displayed on the popup along with radio button.
    Now please let me know how to pass the certificate name and radio button to popup
    Could anyone help me.
    Thanks in advance.

    This is my managed bean code :-
    public class custom {
    private RichDialog dial;
    private RichPopup hellopopup;
    public custom() {
    public void showPopup(PopupFetchEvent popupFetchEvent) {
    // Add event code here...
    RichOutputText newText = new RichOutputText();
    RichSelectBooleanRadio radio = new RichSelectBooleanRadio();
    newText.setValue("Hello");
    dial.getChildren().add(newText);
    dial.getChildren().add(radio);
    public void setHellopopup(RichPopup hellopopup) {
    this.hellopopup = hellopopup;
    public RichPopup getHellopopup() {
    return hellopopup;
    public void setDial(RichDialog dial) {
    this.dial = dial;
    public RichDialog getDial() {
    return dial;
    public void hello() {
    // Add event code here...
    RichPopup.PopupHints hints = new RichPopup.PopupHints();
    hellopopup.show(hints);
    and this is my jspx page code :-
    <f:view>
    <af:document id="d1" initialFocusId="it1">
    <af:messages id="m1"/>
    <af:form id="f1" defaultCommand="cb1">
    <af:commandButton text="commandButton 1" id="cb2"
    action="#{custom.hello}" partialSubmit="true"/>
    <af:popup id="p2" popupFetchListener="#{custom.showPopup}"
    binding="#{custom.hellopopup}">
    <af:dialog id="d3" binding="#{custom.dial}"/>
    </af:popup>
    </af:document>
    </f:view>
    This will work for sure.

  • PHP Form mail

    I used this script
    http://www.visibilityinherit.com/code/php-form-validation.php
    to produce a form and everything worked fine on my site, which I
    was using for testing. When I transferred over to the client's site
    it doesn't send the email. The error and thank you messages work,
    but no email. As I have heard that some hosts block some php files
    with the name 'formmail' I called it something else.
    I have checked and rechecked all the data and only my email
    address and the URLs for the error and thank you pages had to be
    changed, my email is correct, but still not email.
    Any ideas as to what is happening and how I can get around it
    please?
