How Can I Pass A Parameter With Submit Button On Form

I want to create the from that can change product data in mySQL made by PHP. and I have the key column that auto increment and specify each product. When i click to edit product li

Solution 1:

You need to echo the value.

<formid="form2"name="form1"method="post"action="editWeb.php?Key=<?echo$Key?>"/>

You could also use a hidden input:

<formid="form2"name="form1"method="post"action="editWeb.php"/><inputtype="hidden"name="Key"value="<?echo$Key?>" />

Solution 2:

you need to create a hidden input field and place that value in it. and then submit the form

<inputtype="hidden"id="Key"name="Key"value="<?=$Key?>">

Solution 3:

<form id="" name="form" method="get" action="page.php"/>
 <name="" input type="hidden" value="">
 <input type="submit" value="">
 </form>

GET->show hidden value on required page url.generally we use GET to pass values, it depend upon your requirement.
