Passing javascript variable to html or php

ashraf_gawdat · July 10th, 2006, 05:30 PM

I have a page that contains a link to, say a delete product page, and I want the user to insert the code of the product in a javascript prompt box, then passing that code entered to the second page so the code knows which product to delete. And I want it to be passed in the url, as it should be something like (delete.php?code=5) where the user inserted 5 in the prompt box.

I've tried many methods by trying to pass the value to php or to html but failed. Do any one have a good idea?

No Javascript needed:

<form method="get" action="delete.php" name="myForm">
<input type="text" name="code" value="5">
<input type="submit">
</form>

If you really wanted, though, you could replace the submit button with this to do the same thing;

<input type="button" onClick="document.location.href='delete.php?code=' + document.myForm.code.value;">

Though in situation you presented, it's best to use a submit button or an input image.

It seems that you didn't get what I meen. I want the user to click a hyperlink not a submit button, then a prompt box appears waiting the user to enter the code in it, and when he do that he is taken to (delete.php?code=number) where (number) is the number he entered in the prompt box.

Any way I have found a good and simple way to do that with the following code:

Code:

<script>
function get_code(form_name)
{
    var number = prompt("Enter code","");

    if (number != null && number != '')
    {
        document.forms[form_name].code.value = number;
        document.forms[form_name].submit();
    }
}
</script>

Code:

<FORM name="delete_product_code" METHOD="GET" ACTION="delete.php">
<INPUT name="code" value="" TYPE="hidden">
</FORM>

Code:

<a href="#" onClick="get_code('delete_product_code');">Delete Product</a>
