stupid flogging no errors

[offsprg01]

well this is causing me issues, mainly becuase the server admin won't turn on php errors. so the script just stops when it's broken making it really hard to trouble shoot. anyway here's the code that causing the issues.

 

<?php 

function truncateTickerMessage($String, $limit = 100) {
		$len = strlen($String);
	if ($len > $limit) $String = substr($String, 0, $limit) . '...';
	return $String;
}


require_once('../Connections/TestDB.php'); 

mysql_select_db($database_TestDB, $TestDB);

$query_Ticker = "SELECT * FROM Ticker ORDER BY TickerDate DESC LIMIT 5";
$Ticker = mysql_query($query_Ticker, $TestDB) or die(mysql_error());
$row_Ticker = mysql_fetch_assoc($Ticker);

$c = 0;

do {
	$c = $c++;

	$tickerLink[$c] = $row_Ticker['Link'];

	$tickerTitle[$c] = truncateTickerMessage($row_Ticker['Title']);
	$tickerMessage[$c] = truncateTickerMessage($row_Ticker['Message']);

} while ($row_Ticker = mysql_fetch_assoc($Ticker));

?>

 

can you guys seen anything i'm missing? it all looks correct to me.

What's the problem?

 

As well, why don't you run error_reporting(E_ALL) at the top of your script? That's not something that the server admin will usually block against, as it's specific to that script.

[offsprg01]

this is the problem

and running

 

error_reporting(E_ALL)

 

returns no errors

you'll also have to do ini_set('display_errors', 1);

[Balmung-San]

It could be that you're not outputting anything, at least not with this code.

 

As well, $tickerLink, $tickerTitle, and $tickerMessage are all local within the loop, at least that's what I can tell from the little code you've given us.

[offsprg01]

you'll also have to do ini_set('display_errors', 1);

 

still returns the same blank back ground

 

and here's the output code, i know this code worksm if i run it with some test data in the variable it works.

 

<script type="text/JavaScript">
<!--

//ticker java

        //scroller width
        var swidth=310;

        //scroller height
        var sheight=15;

        //background color
        var sbcolor='#000000';

        //scroller's speed
        var sspeed=1;
        //messages are set below:

<?php require('/includes/tickerSQL.php'); ?>

        var msg=''



        msg +=
        
            '<a href="<?php echo $tickerLink['1'] ?>" target="_blank" title=""><?php echo $tickerTitle['1']; ?></a><br />'+
            '<?php echo $tickerMessage['1']; ?><br />'+
            '<br />'+                     
            

        '';

 

 

[Balmung-San]

Use $tickerLink[1], $tickerTitle[1], and $tickerMessage[1]. You're trying to use the string '1' as the key, when the key is the numeric 1.

[offsprg01]

i tried replacing the sting 1 with numeric 1, still did not work. the error is in the included tickerSQL.php, which is the first code i posted

 

i know the code in my last post works becuase when i replace

 

<?php require('/includes/tickerSQL.php'); ?>

 

with

<?php $tickerLink[1] = '#'; $tickerTitle[1] = 'Title 1'; $tickerMessage[1] = 'Message 1'; ?>

 

it works.

 

i currently have it replace now, if you'd like to see it working

[Balmung-San]

Then the issue has to be scope.

 

Try declaring $tickerLink, $tickerTitle, and $tickerMessage before the require statement.

[offsprg01]

what do you mean by scope?

[Balmung-San]

Scope is basically where the variable can be seen. Since the first use is within a while loop in the included file, I'm thinking the variables stay local to that loop, and die once the loop is done.

[offsprg01]

well i tried declaring them but still got nothing. i may try rewritting my code to get rid of the loop. that would sure be a dirty way to do it though.

[offsprg01]

well i found one problem it was this

 

<?php require('/includes/tickerSQL.php'); ?>

 

should have been this

 

<?php require('includes/tickerSQL.php'); ?>

 

but now i get no data in my variables

 

check out

 

http://www.harwoodmarketinggroup.com/WIP/index.php

 

to see what i mean. the black box that says click here at the top of the screen.

[Balmung-San]

It's probably this line:

 

$c = $c++;

 

Instead, use either:

 

$c = ++$c;

 

or just:

 

$c++;

[Ninjakreborn]

I see the data.

If it's not working in ie, but it's working in firefox (which is what I am checking it in), it's a browser issue.

[Balmung-San]

Yes, I'm currently using IE (blah, company standards) and I can't see the data.

 

In that case, it's an issue with the JavaScript.

[offsprg01]

lol i finally found the error. it was a stupid aphostrophe in the database. i just got rid of it. but for future refrence, how do you escape something coming from a db if you don't know it's there or if it is there where it will be?

 

thanks for the help though.

[hitman6003]

The addslashes function will escape single and double quotes for you.

Alternatively, use htmlentities

When trying to trouble shoot a blank page, here's what I do.

 

At the very top of the script before anything:

 

echo "hi2u"; exit();

 

If I reload the page and don't see hi2u, 99% sure its a syntax error.

 

If I do see hi2u, just cut the echo line, move down a small chunk, and re-paste it.  Do this until you narrow down the one line that is causing it to blow up.  You'll often find is a bad file path, undeclared function, etc.
