Instead of typing
<?php echo htmlspecialchars($title) ?>
you could use
<?= htmlspecialchars($title) ?>
This is shorter and better way to echo out something
And also instead of creating variables above for old values you can use something called null coalesce operator like this
<?= $title ?? " " ?>
This will check if that variable exists or not. if it does it echos that out
but if it doesn't it will echo that other empty string that is after those two question marks
so that you don't get undefined variable error

How can we pass array of errors from backend to frontend with help of header function ? Please explain sir 😌

Very good videos on processing form in PHP.

However I have a question:
1) In creating a contact form, a <textarea> element is used for user messages (which are usually multi-lines) instead of a textbox element. Please advise how to persist the entered information to the <textarea> as there is no value attribute in <textarea> element.


Thank you.

Pure gold as always Shaun. Will there be a 'form submitted' confirmation message before the homepage redirect or a banner on the homepage with 'form submitted successfully' ? From a UX point of view that would be preferable, no? Otherwise users may not be sure if the form was actually sent prior to the redirect.

[DMKano]

I have a question about 'htmlspecialchars()'. Why we should use it even though we restrict earlier what user can and cannot enter in the forms using 'preg_match()'? And why we do this when we outputting the data and not when we inputting them?

[deboparnabanerjee]

The idea of retaining the values was wonderful!! I was wondering how to do that if it were a checkbox?

[anonymouseverx]

This is not just a tutorial, it's an educational class for who love server-side programming and projects. Thanks, Shaun.
(Shaun, I have a problem with the ingredients field. When I submit the form, the value of this field fades out, while the other fields are ok. Where is the problem? (I check everything, but it doesn't work.)

Hey ninja thanks a lot for these videos have been very helpful. Do you recommend jumping to Laravel after this series or is there more to learn? Thank you!
