Return key doesn't Sumbit

Anon

Hi guys,

I made a form with one <input type="Text"> and one Submit button. When the focus is on the Text-control and I press the Return key (Enter), the form submits, but the $submit variable in PHP is then set to "" (empty). The name of the button is "submit" and it's value is "Submit" and I use method="post", so it should be working. But why doesn't it? TIA.

the submit button it self doesn't carry the data... If you had writen <input type="Text" name="stuff"> then the text in the text field would be put in the variable HTTP_POST_VARS[stuff] (or HTTP_GET_VARS[stuff] if you used get).. I hope this solves it for you...

Hi Andreas,

I know the submit button it self doesn't carry the data, but I use it to check if the form has been submitted, or that I have to show a new, fresh, empty form.

<?
   if ($submit) {
      // do stuff
   }
   else {
      // show form
   }
?>

If I press the Enter key, sometimes (mostly it works correct) I get no value for $submit or $HTTP_GET_VARS["submit"]. All other needed vars are correct and available.

You should just check to see if your textbox has been filled out, instead of checking if you were submitted. I guess if you wanted to check that it was a post instead of a get that you could, but that isn't the right way.

I recommend just checking if the request had any valid values on it. That way you are building an open interface that you can reuse easier.

Anways, email me...

Dear Vincent:

I had the same problem in my form. It was just a simple form where someone would enter a record number to search for.

The problem is, the enter key submits the form, but unless you actually press the submit button, that submit value isn't sent along. What you have to do is trick the browser into thinking the submit button has been pressed using an invisible field.

Here's what I mean: I would use an if else to determine if the submit button, which I named "ape", was pressed. If it was, it would process the query, otherwise it would return this form:

<form method="post" action="<?php echo $PHP_SELF?>">
Select a record to edit:
<input type="text" name="ednum" size="7" maxlength="7">
<input type="submit" name="ape" value="Edit this record!">
</form>

But if the user hits "enter" instead of clicking on the select button, the value of "ape" will remain null, and the page will think nothing has been selected, and display the form again. It's still sending the value of "ednum", but that's not what the ifelse is testing for, it's looking for the existence of "ape".

So you trick it into thinking the select button has been pressed when the user hits enter by including one little line before the tag for the submit button:

This line gives "ape" a non-null value that the ifelse statement will respond to.

Hope this helps!

Thanks for the help. I was looking for a solution to the same problem.
Your solution worked the first time.
