confirm box in php with yes no option code example

Example: write confirm dialog box if yes then run function using php

You can handle the attribute onClick for both i.e. 'ok' & 'cancel' condition like ternary operator

Scenario: Here is the scenario that I wants to show confirm box which will ask for 'ok' or 'cancel' while performing a delete action. In that I want if user click on 'ok' then the form action will redirect to page location and on cancel page will not respond.

So below code is working properly for me :
onClick="return confirm('Are you sure you want to Delete ?')?this.form.action='<?php echo $_SERVER['PHP_SELF'] ?>':false;"

Full code
<input type="submit" name="action" id="Delete" value="Delete" onClick="return confirm('Are you sure you want to Delete ?')?this.form.action='<?php echo $_SERVER['PHP_SELF'] ?>':false;">
And by the way I'm implementing this code as inline in html element using PHP. so that's why I used 'echo $_SERVER['PHP_SELF']'.

I hope it will work for you also. Thank You
