PHP标记内的HTML表单

Question

I want to make a form that submits data from user input into a database. However, when making the form, it does not appear in the browser.

Here is the code.

echo '<form name="submit" method="post" action="reservation_confirm.php">';
echo '<Confirm: <input type="submit" name="confirm" value="confirm">';
echo '</form>';

Answer 1

You have a less-than sign < to many.

Change:

echo '<Confirm: <input type="submit" name="confirm" value="confirm">';
//----^ remove

To:

echo 'Confirm: <input type="submit" name="confirm" value="confirm">';

Answer 2

It's because of less sign on your second line. It is considered HTML opening tag. Try this:

echo '<form name="submit" method="post" action="reservation_confirm.php">';
echo '&#60;Confirm: <input type="submit" name="confirm" value="confirm">';
echo '</form>';

Or simply remove it.

Answer 3

It's not a good practice to put HTML code inside PHP code. What you can do is this:

<?php
//Some PHP code here
?>
<h1>Some HTML code here</h1>

This also works:

<?php
if(something) {
?>
    <h1>This is going to be displayed</h1>
<?php
}
?>
