Hello people,

I've been trying to get this to work all afternoon without any luck (it's been quite a productive day...)

I'm writing an add-on for a simple forum script in php.
What I want to do is to open a popup window, select an image to upload and return the BBCode into the form field of the opener page.
The upload works like a charm.

This is what I have so far:
opener page (found this with google):

<SCRIPT LANGUAGE="JavaScript">
<!--
function showList() {
sList = window.open("uploadimg.php", "list", "width=600,height=450");
}
function remLink() {
if (window.sList && window.sList.open && !window.sList.closed)
window.sList.opener = null;
}
// -->
</SCRIPT>
<input type="button" value="Upload Image" name="Upload Image" onClick="showList()" />

opened page:

$result="[url=".$forumurl.$idir.$file_prefix.$imagefilename."][img]".$forumurl.$tdir.$file_prefix.$imagefilename."[/img][/url]";
echo "<input type='text' size='75' maxlength='255' name='select' value='$result' />
<input type='submit' value='copy to form' onclick='insert(window.opener.document.forumpost.req_message.text,'\\\\Q$result\\\\E')' />";

this will return an error and does not do what i want
I'm thinking it has something to do with special characters, hence the \\Q\\E, but I could be wrong all together obviously...
anyone any ideas?

Can't see what your insert function is doing, but here is what I use.

This code is either actually in the pop-up window or in an external file linked to by the pop-up window. Note I'm not storing the pop-up form data anywhere. I don't know that you need all the stuff for special characters because all it's doing is taking the data from the pop-up window's text box and putting it in the opener's text box.

The pop up form would look something like:


<form onSubmit="populate(this,'opener_text_box'); return false;">
<textarea name="content" id="content"></textarea>
<input type="submit" value="Populate Opener">
</form>

The JS:


function populate(form,field) {
if (window.opener && !window.opener.closed) {
var target = window.opener.document.getElementById(field);
if (form) { target.value=form.content.value; }
window.close();
}
}
