What are some common pitfalls when using target attribute in PHP files for opening popups?
When using the target attribute in PHP files to open popups, a common pitfall is leaving the target attribute blank or using "_blank" which can lead to security vulnerabilities such as cross-site scripting attacks. To solve this issue, always specify a unique target name and avoid using "_blank" to prevent potential security risks.
<a href="popup.php" target="popup_window" onclick="window.open('popup.php', 'popup_window', 'width=400,height=400'); return false;">Open Popup</a>
