I'm making a simple contact form which works and I would like to have the user add in either their phone number OR their email. Both are fine, but at least one is required. I don't want to require both. Anyway, I created an if statement in my php code which works but when I have it return to the form, of course the form has been cleared of the user input.

I personally hate it when that happens to me, so I want to make sure that whoever is filling out the form doesn't lose their information

Hi all, I have a problem for sanitizing / validating a web address input. My personal favor is doing it with regex. I made a simple example with preg_replace <?php if (!empty($_POST['wbddrss']) ) { $wbddrss = $_POST['wbddrss']; $wbddrss = trim($wbddrss); var_dump($wbddrss); $validate = preg_replace('/<>/' , '', $wbddrss); var_dump($validate); } ?> But I would like to replace all chars that do not meet what is allowed.

First of all, i am particularly focusing on the cross-reference across files feature. What is it?

If we don't need the benefits from this feature, why not use the free and quick editor - Notepad++ ? Many PHP dev tools are equipped with the reference feature. B

I was looking through some ways to validate email. I saw the one on w3schools, but that is a basic one, so I started to code something more complicated adding all those if, else if, else statements, etc. Then I came across this... function validateEmail(email){var allowed=/^([a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$)/; return allowed.test(email);} Is something that simple sufficient enough? Everything seems to look as if it would work. Also, what does the "$" do?

I created a php contact form for our Technology department in a school district. I would like to make a particular field required or optional based on the choice made in a dropdown menu.So, if the user chooses the Hardware or Software category, I want the barcode field to be required. If they choose Username/Password, I want the barcode field to be optional.Here is the part of the code that is validating fields: function died($error) { // your error code can go here echo "<b>We are very sorry, but there were error(s) found with the form you submitted.</b><br /> &
