[RESOLVED] Pl, help...Form Submit issue.

pradee

Hi,

I came across a problem when submitting a form which i managed to correct, but still i have no idea why it happened. I think it is a HTML issue.

Form is in a HTML file which contains a text box and a submit button, on submit (form's action calls it) it redirects to another form which is php. In the 2nd form, i check if the submit is valid as below:

if ( isset( $_POST['submit'] ) )
{
......
......
}

Well, the issue is, if the user presses the enter key to submit the form after entering a value for the text box, the above condition doesn't satisfy, so it doesn't work, but it works on mouse click. So, what i did to overcome the problem was to check if the text box contains a value or not,now it works.

$search_key = $_POST['serach_key'];
if ( isset( $_POST['submit'] ) || $search_key !="")
{
......
......
}

Why I'm confused is, some other form with exact phrase works when its called from an HTML page through form submit.

However, this problem occured in IE 6 & 7, not in Firefox.

Please let me know what the cause of this problem was.

Thanks a lot.

Have a nice day!

I also have encountered the same problem on several occations. I dont know the reason as to why this happens. What i did was wrote a key trap function in javascript to capture the pressing of the enter key. Once i managed to capture that i could call the a javascript function whici will submit the page similar to mouse click.

An easy way to solve the problem (but not the cause of the problem) is to use a hidden value instead of the value from the submit.

Some broswers(IE) don't post the submit button's name/ values when you use enter to submit the form instead of clicking. You can check this if you do a

print_r($_POST);

on the action page.

As prianha said use a hidden input field and use that to check if the form was submitted or not

//in form
<input type="hidden" name="form_submit" value="1" />
<input type="submit" value="submit" />


//action page
if(isset($_POST['form_submit']){
 //...........................
}

You could also check by using if (!empty($_POST))
