if statement not triggering

[RalphLeMouf]

Hello,

 

I have been banging my head against the walla and trouble shooting this for days now. It seems so simple, yet there is something going on that I can't figure out. Thanks so much in advance for the help

 

I am currently limiting comments and replies to comments on my social network. I have successfully done so except on the replies for one page, I can not get php to display an error with a simple if statement that should be firing when the submit button is hit.

 

It's important to know that I have TWO pages being used. The main structural page and then the content page that is included in the structural page.

 

Here is the code:

 

[code]if(isset($_POST['sub_comment_reply'])) {
if($_POST['reply'] == "" ) {
$valid = false;
$error_msgs_reply[] = "Whoops! You forgot to write your reply.";
}else{

	$query = "SELECT COUNT(*) FROM `CysticAnswers_replies`
              WHERE `FromUserID` = $auth->id
                AND `date` = CURDATE()";
    $result = mysql_query($query, $connection);
    $post_count = mysql_result($result, 0);
	$max_reply_per_day = 5;
	$error_msgs_replies_max[] = "Whoops! You have reached your limit of replies for the day."; 




    if($post_count >= $max_reply_per_day){
			$valid = false;

    }
    else
    {
	$query = "INSERT INTO `CysticAnswers_replies`
										( `QuestionCommentID`,
										  `FromUserID`,
										  `comment`,
										  `status`,
										  `date`,
										  `time`
									    ) VALUES (

										'" . mysql_real_escape_string($_POST['comment']) ."',
										'" . $auth->id ."',
										'" . mysql_real_escape_string($_POST['reply'])."',
										'active',
										'" . date("Y-m-d") . "',
										'" . date("G:i:s") . "')";

		mysql_query($query, $connection);



}

// this is from the page that is included, to echo the error but the if is not triggering
<?php if(isset($_POST['sub_comment_reply']) && $post_count >= $max_reply_per_day && $valid = false) {


			foreach($error_msgs_replies_max as $msg) { ?>
			<div id="error_x">
			<?php echo $msg; ?>
			</div>
			<?php }
		}?>

[/code]

Which one isn't working?

use print_r($_POST); to see the contents of post.

I don't know if this will fix your problem, but you need to use the comparison operator here:

 

$valid = false

 

should be:

 

$valid == false

... but you need to use the comparison operator here:

 

$valid = false

 

should be:

 

$valid == false

 

No... he is not doing a comparison in that line of code.. just assigning a Boolean value to the variable $valid

Doh!

Sorry. I was actually quoting this line of code:

 

<?php if(isset($_POST['sub_comment_reply']) && $post_count >= $max_reply_per_day && $valid = false) {

I didn't realize what I had typed was a complete line of code from another part of the file. You need to change THIS line so that (I'm assuming you want):

<?php if(isset($_POST['sub_comment_reply']) && $post_count >= $max_reply_per_day && $valid != false) {

or it may be:

<?php if(isset($_POST['sub_comment_reply']) && $post_count >= $max_reply_per_day && $valid == false) {

Either way, the code you have now will set the $valid variable to false no matter what, and the IF statement will fail.

My logic tells me that I want

$valid == false

because I want it to only trigger IF false. However I tried all of your suggestions and it's still not echoing. The only time I can get the message to show up is when I do

<?php if($post_count >= $max_reply_per_day ) {

wrapped around the error message. Problem is, that it shows up WHEN the page loads, not after the button is submitted. It's a triggering problem. I've

die()

all the variables and they are working properly. Its not reading

$if(isset($_POST['sub_comment_reply']))

for a trigger for some reason. Gonna go back and check that again

[RalphLeMouf]

this may help as this is the code chunk that is also involved within the if statement that is NOT firing still

 

<form name='comment_reply' action='<?php echo $_SERVER['REQUEST_URI']; ?>' method='post'>
					<div class="respond_body_future round_10px">
						<div class="respond_arrow_future"></div>
						<div class="respond_tail_future"></div>
						<div class="respond_data_future">
							<textarea id="reply_to_<?php echo $result['id']; ?>_textarea" name='reply'></textarea><br />
							<input type='hidden' name='comment' value='<?php echo $result['id']; ?>' />
							<div class="respond_nevermind">
								<a href="reply_to_<?php echo $result['id']; ?>">nevermind</a>
							</div>
							<input type='submit' class="submit" name='sub_comment_reply' value='Reply' />
						</div>
					</div>
				</form>

You basically have a whole page that doesn't work. Snippets of code from that page don't really help us because the posted snippets of code are each doing what they were written to do. The problem is in something that's occurring somewhere between those snippets of code.

 

Without all the logic on the offending page that is needed to reproduce the problem, its not directly possible to help you with the logic on your offending page. I'm going to guess that you have overwritten $_POST['sub_comment_reply'] at some point between where it is set at the top of that posted code and where you test it again in the included code. The problem could even be in how you are including that code.

 

When you were dumping the values, were you doing that in the included file's code or was that in the main file's code?

 

Posting the full relevant code will be the quickest way of getting a solution.
