Bug description: form buttons of type "image" dont send "submit" $_POST variable in IE
Description:
------------
I don't see how this wouldn't be a common bug, nonetheless I couldn't find
it in the database..
when using an input of type "image" (i.e. you want to use an image of your
own to submit a form instead of the ubiquitous submit button), submitting
a POST, three variables should be transferred = the value of the submit
button you clicked, and the x and y coordinates of where on that
particular button you clicked.
Mozilla gets all three variables in the $_POST associative array no
problem; for some reason Internet Explorer (I have version
6.0.2800.1106.xpsp2.030422-1633) does not get the value variable, only the
two coordinates.
While in practical terms the problem is not huge (after all, the name is
still located in the x and y coordinate associative array keys), but a) it
seems like this might be a problem for quite a few others, and b) grabbing
the names from the x and y vars is both inelegant and a slight PITA.
a quick phpinfo() shows that it doesnt seem to be a syntactic or semantic
error, the $_POST array just isnt being given that value in IE.
any suggestions?
Reproduce code:
---------------
//calling form
<form action="form.php" method="post">
<input name="foo" type="image" value="submit" src="foobutton.jpg">
</form>
// form.php
foreach( $_POST as $key => $value ) {
echo $key."=>".$value."<br>";
}
Expected result:
----------------
What should happen:
foo => submit
foo_x => 100 //x-coord.
foo_y => 55 // y-coord.
Actual result:
--------------
What does happen:
// $_POST["foo"] doesnt exist, but only in IE
foo_x => 100 //x-coord.
foo_y => 55 // y-coord.
