php problem with IE (possibly session related)

Abraham · 5 Oct 2007 at 13:24

i've got two problems with a simple e-shop that i've written the code for
i think they may boil down to being the same problem but i'm not sure:

1st up:

simple login:
just takes a user id as input, checks against the db and forwards to the correct page if it exists

works for firefox but not for IE - if you press Enter to submit the form (if you click the login-submit button it works as in firefox)

2nd:

shopping basket:
the fundamental part that isnt working is the creation of a session variable which is called later in the page
code as below:

PHP:

$result = mysql_query($query);
$thisorder = mysql_insert_id();
}
if ((!isset($_SESSION['order'])) || ($_SESSION['order'] == NULL))
{
$_SESSION['order'] = $thisorder;
}

as with the login it works fine in FF but not in IE.

I will keep putting debug echos in to try and find where it's going wrong, but kind of desperate to solve this, i've been testing throughout dev in FF unaware there could be any incompatibilities like these
any suggestions will be gratefully appreciated

1st thing is purely down the html used in your form - i have forms that work fine in IE when you press enter. :confused:

maybe IE is fussy about all tags being closed properly? (just guessing. me is html noob)

2nd thing - haven't a clue why it works in one browser and not another.

on further investigation the 2nd one isnt because of that bit of code, was further up the tree than i thought

Code:

if(isset($_POST['update']) || isset($_POST['submit']))

that's the bit that's actually causing the problem
and i've an inkling it may be to do with the submit button on the previous page being an image

Code:

<input name="submit" type="image" src="images/next.gif" alt="Submit Button" value="Order">

just looking into whether there's a known problem with submitting a form like that in IE

dont think it can be as a result of that ^ as it seems to work fine on other forms throughout the site, but this is the only time i check for $_POST['submit']

edit: just frigged about with it and it looks like that was the problem
have worked round it by setting a session variable on the 1st page and checking for that rather than the submit button

still stumped by the login click but not enter jobbie though

i just tried one of my previously fully working forms with an image for a submit button and IE doesn't like it. so the image is definitely the problem. as for a workaround, sorry haven't a clue.

from what i found the 1st problem is a bug to do with only having one input on a form

the solution on there of having a 2nd hidden field has worked a treat
i'd rather not frig it like that but time is of the essence at present so this does the job

bizarre. my form that didn't work with an image has 3 inputs (1 text, 1 password, 1 hidden). never mind, at least yours is working.

don't use an image for submit, use a submit button and assign it the style for an image:
(need to identify it with a class or id for css)

Code:

<input type="submit" class="submit"/>

Code:

input.submit {
  background: transparent url(/images/submit.gif) no-repeat;
  display: block;
  height: 20px;
  width: 20px;
  overflow: hidden;
  padding-top: 30px;
}

ahh, good solution, will bear that in mind for future ref

forgot to add "border: none;" to the style, too.
