停止验证后返回空的PHP表单输入

Posted 2021-02-26

This is a short and sweet snippet that will save the users form input after php runs validation and returns false. Very good for User Experience!

<?php if(isset($_POST['FORM_INPUT_OR_TEXTAREA_NAME_GOES_HERE'])){ echo $_POST['FORM_INPUT_OR_TEXTAREA_NAME_GOES_HERE']; } ?>
 
SAMPLE OF A FORM INPUT:
 
<input name="name" size="20" value="<?php if(isset($_POST['name'])){ echo $_POST['name']; } ?>">
 
SAMPLE OF A FORM TEXTAREA:
 
<textarea name="comments" rows=5 cols=20><?php if(isset($_POST['comments'])){ echo $_POST['comments']; } ?></textarea>
