Hy developers i have this problem

    <?php if (isset($_POST['title'])) : ?>
        <?php $idea_title = $_POST['title']; ?>
    <?php endif; ?>
    <?php if (isset($_POST['text'])) : ?>
        <?php $idea_text = $_POST['text']; ?>
    <?php endif; ?>

<?php $new_idea = array('title' => $idea_title, 'text' => $idea_text);  ?>
<?php $new_idea_keys_string = implode(', ', array_keys($new_idea)); ?>
<?php $new_idea_placeholders = ':' . implode(', :', array_keys($new_idea));  ?>

Warning: Undefined variable $idea_title in /in/bO5i2 on line 11 Warning: Undefined variable $idea_text in /in/bO5i2 on line 11 i get this error i don't know why because i thinlk that i alredy defined the variables in the first IF

You only define the variable when the `if` condition is true. You need to give the variable a default value in other cases. – Barmar Sep 05 '21 at 22:39
Yes brother because i want to update informations in the server, so that i want to accept informations only when the uset press Submit, i don't know if i'm right cause i'm new in PHP, and thank's again – Fred Lord Sep 05 '21 at 22:43
I'm a bit rusty on PHP, so I'll ask: why does every line have a PHP opening and closing tag? – Robson Sep 05 '21 at 22:43
All the code that uses `$idea_title` needs to be inside the `if`. – Barmar Sep 05 '21 at 22:44
@Robson It doesn't need it, it's just a style issue. – Barmar Sep 05 '21 at 22:44
@Barmar That makes sense - thanks for confirming. – Robson Sep 05 '21 at 22:48
@Robson just styling, i can do only one tag wit all the lines, same result – Fred Lord Sep 05 '21 at 22:49
