How to Pre-Select an Option in a Dropdown Box Using PHP

In HTML, you can set the selected item in a dropdown box using the selected attribute. However, in the code provided, the selected attribute is being set using a PHP variable, which can be confusing.

To pre-select an item in a dropdown box based on a database value, you need to set the selected attribute of the correct option tag to "selected."

<code class="html"><option value="January" selected="selected">January</option></code>

In the PHP code, you would assign the selected value to the appropriate option tag as follows:

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

This code checks if the value of $row['month'] is equal to 'January'. If it is, the selected="selected" attribute is added to the option tag. Otherwise, the empty string (``) is added.

It's generally considered better practice to create an array of values and loop through it to create a dropdown. This makes the code easier to maintain and understand.
