How to Use PHP to Preselect an Item in a Drop-Down Menu?

Selecting an Item in a Drop-Down Box using PHP

The question arises as to how one can select a particular item from a drop-down box using PHP code like this:

<code class="php"><select selected="<?php print($row[month]); ?>"><option value="Janurary">January</option><option value="February">February</option><option value="March">March</option><option value="April">April</option></select></code>
Copy after login

The objective is to allow users to select their existing month setting on an edit page.

Solution:

To select the desired item, it's necessary to set the 'selected' attribute to the correct option tag. Here's the modified code:

<code class="php"><option value="January" selected="selected">January</option></code>
Copy after login

In PHP, this translates to:

<code class="php"><option value="January" <?php echo $row['month'] == 'January' ? ' selected="selected"' : ''; ?>>January</option></code>
Copy after login

Alternative Approach:

For a cleaner solution, consider creating an array of values and looping through it to generate the drop-down options. This ensures consistent and readable code.
