How can I create a custom button for opening a form?

Question

I have a parent form having child forms. In my main form I want to create custom buttons for opening child forms. I want to use master-detail form but there are more than one child forms, and in master-detail form I can only create one detail form. So I will create a form based on a table and in that form I will call the child forms by custom buttons. Can I do that?
Thanx,

This can be easily done. First open up two instances of your Portal. In one window, you will need to go into your component you wish to link FROM. In the other window you will need to go into your component you wish to link TO. In the component you wish to link TO there will be a moduleid. Note this somewhere. Then, you will see an area that says: "Call Interface: Show". Click on this. (In the window you are linking to.). In this window, you will see a bunch of stuff. At the bottom you will see a URL call. This is the call you need to use. At the top, it explains each piece of the URL call. Just subsitute YOUR appropriate information into the URL call. In the form you wish to link FROM, create a button. Once you create this button, it will appear at the bottom, click on it and you will see an area to insert a Javascript. Click the onClick and insert:
//this is the variable you want to pass from one form to the other
get_field_name = getField(this.form,'COLUMN_NAME_IN_DATABASE');
//this is so you can open the "child" form
window.open('/pls/cc_prod/DAD_NAME.wwa_app_module.link?p_arg_names=_moduleid&p_arg_values=MOD_ID_HERE&p_arg_names=_sessionid&p_arg_values=&p_arg_names=COLUMN_NAME_IN_DATABASE&p_arg values='+GETFIELD_NAME+'&p_arg_names=_COLUMN_NAME_IN_DATABASE_cond&p_arg_values=%3D');
In the fourth tab, where it says, "....before displaying form" insert the following: (This will tell the form how to handle the getField function.)
htp.p('<script language="JavaScript1.3">
< !--
function getField(form,fieldName)
var objName = "";
var tmp = "";
var dAction = "";
var sel_idx = 0;
var cnt = 0;
var instance = 0;
var slicedName;
var fillData = new Array();
for (var i = 0; i < form.length; i++)
slicedName = form.elements.name.split(".");
tmp = slicedName[2];
instance = parseInt(slicedName[3],10);
if (!tmp)
continue;
objName = tmp;
if (objName == fieldName)
return form.elements[i].value;
//-->
</script>');
I hope this helps.
