I am working on project and came across the problem: When i click a button on the e.g. //website/manageuser.php I want the value of the button in the //website/edituser.php
I tried using the <value> tag in a button but failed. I wasn’t able to manage to transfer the value through the files.
My manageuser.php looks like this:
After i press the e.g. "Delete" button, i get forwarded to the /deleteuser.php where I want to print the value behind the button. Unfortunatly, it isn’t working with a StackOverflow Javascript script.
Image of my /deleteuser.php:
Code of the important part of manageuser.php:
<table>
<tr>
<?php
$query = "select * from users";
$records = mysqli_query($con, $query);
while($data = mysqli_fetch_array($records))
{
?>
<th>
<p/>
<?php
print($data["full_name"]);
?>
<button type="button" value=" <?php print($data['full_name']) ?>" onclick="window.location.href='./edituser.php'">Edit</button>
<button type="button" onclick="window.location.href='./deleteuser.php'"> Delete </button>
</th>
<?php
}
?>
</tr>
</table>
Code of the important part of deleteuser.php:
<!DOCTYPE html>
<html>
<body>
<script>
var str1 = document.getElementById("btn").innerHTML;
var str2 = document.getElementById("btn").value;
document.write("Button text: "+str1);
document.write("<br>Button value: "+str2);
</script>
</body>
</html>
>Solution :
You don’t need the value. Just append the value from $data as a query parameter to the URL.
<button type="button" onclick="window.location.href='./deleteuser.php?id=<?php echo $data['id'] ?>"> Delete </button>
Then in deleteuser.php you can use $_GET['id'].
