nagasea

I already search all over this form and still can't figure out the solution.
Can someone help me with this :

working one (without image as the submit button)

index.php
<form action=\"admin_index_editclient.php\" method=\"post\">
<input type=\"submit\" name=\"action\" value=\"Modify\">
</form>

functions.php
if ($_POST['action']=="Modify") {
echo "workssss...";
}

now how to make the modify button into image i tried with javascript and it's not working

With some javascript you can do the following:

<form name=\"MyForm\" action=\"admin_index_editclient.php\" method=\"post\">";
<input type=\"hidden\" name=\"action\" value=\"Modify\">";
</form>";

<img src=\"mypic.gif\" onClick=\"document.MyForm.submit();\">";

Line 153
Char 1
Error: Object doesnt support this property or method

And in line 153 : <b>$companyname</b><br> ";

You can use input type as image, as so:

Just a warning, you will not be able to use the name field anymore to get some value from the input image tag. Like if you had:

if you did:

if($_POST['myButton'] == "send")
<do something>

the above if statement will not do anything. If you have multiple buttons, as images, you are using in a single form, will need to use hidden tags to distinguish the different buttons. Or just create a form for each button where the forms action is directed to the same url. In the other url, you can distinguish the buttons with the hidden tags from the form.

I remember seeing something in the PHP manual about using the image input type. http://www.php.net/manual/en/language.variables.external.php was the page, if I recall.
