Input type image causing confusion

I currently have the following code:

<form action="process.php" method="POST">
<fieldset class="form-search">
    <input type="text" class="input-text" name="keyword" value="Enter Keyword / Catalogue Code" id="textBox"/>
    <?php echo $form->error("keyword"); ?>
    <input type="image" class="catalog_search_top" name="search" alt="Search" src="../images/search_form_button.png" />
</fieldset>

My problem is that the image when submitted isn't doing the same as if its image type submit.

When submitting the form with the code I provided, woul开发者_运维问答d it be expected that it would go to form process.php and send $_POST['submit']?

Thanks

if you use a image as submit button you will have in php $_POST['search_x'] and $_POST['search_y'] instead of $_POST['search']

when using an image button to submit it'll simple be a POST.

so check:

if ( $_POST )
{
    // process form
}

Or you could use - based on the 'name' of the image input:

if ( isset( $_POST['search'] ) )
{
    // process form
}

yip sorry as it's an image it posts co-ordinates, so search_x and search_y as stated.

Just change name="search" to name="submit", it'll work as you want.

But why you need get value for $_POST['submit']? If you want to detect your page has received a request, just use this code:

if ($_SERVER['REQUEST_METHOD'] == 'POST') {
     // Do some thing...
}

I think it better!

your field name first input is 'keyword', so in process.php try change $_POST['submit'] with $_POST['keyword'].
