How can i possibly preserve the value of the <input> field if submitted wrong? I have a form that will be submitted to a php page. The PHP page will then check if that is correct or not.
Ex. if the user input google the PHP page says it is wrong. I want google sent back to the input field.
分享 You can access the value using the $_POST or $_GET super-global. Depending upon the form submit method, you can do:
<input type="text" value="<?= (isset($_POST['field'])) ? strip_tags($_POST['field']) : '' ?>" name="field" />
If your method="get", you'll need:
<input type="text" value="<?= (isset($_GET['field'])) ? strip_tags($_GET['field']) : '' ?>" name="field" />
