PHP - Newby: Help To Debug Application Which Outputs Blank Pages

Hello. 

Assuming that I have two variables:


$exURL=@$HTTP_REFERER;

$goodURL = 'http://www.SomeSite/login/';


How can I check if the two URLs match each other?

Regards

<?php
$i = 2;
$i = $i++;
echo $i;
?>

Output of above code is 2.

<?php
$i = 2;
$p = $i++;
echo $i;
?>

Output of above code is 3.
 
Why this difference? I mean how these codes are processed to give an output?

hmmmm my last post got deleted due to my naughty url:-(

Anyway its not spam :-(
hear is my real problem. I HAVE this form in a iframe in a drupal site.....I followed many tutorials but it seems fine?

It keeps downloading the actual php file instead of posting to my email?

This code is responsible for authenticating the user upon logging in. I went ahead and updated the mysqli portion to PDO. As you can see I var_dump some variables near the end. Variable $row prints out as array(1) { [0]=> array(9) { ["username"]=> string(4) "test" ["password"]=> string(60) "$2y$10$uQEUsIwm0usWyZjWk/vo8e90e867oPLBu3ThKCk1aUseMcQuuHrVq" ["avatar"]=> string(15) "assets/soap.jpg" ["doc"]=> NULL ["las"]=> NULL ["email"]=> string(13) "test@test.org" ["c_status"]=> string(1) "0" ["account_age"]=> NULL ["bio"]=> string(4) "test" } }. The other three print out as NULL. What exactly is going on here?

Hi guys,

I have a simple query he

      $sql="SELECT user_id FROM $tbl_name WHERE email='$loginuseremail' AND password='$loginpassword'";
      $result=mysql_query($sql);
      $row = mysql_fetch_assoc($result);
      
//START SESSION   
      session_start();
         $_SESSION['username']=$loginuseremail;
         $_SESSION['user_id']=$row;
   
         echo $_SESSION['user_id'];   

It should obviously output an ID number but instead I just get the word 'Array'. If I remove the  mysql_fetch_assoc() I just get 'Resource ID #4'.

Can anyone point me in the right direction?

Thanks!

I have a piece of code that outputs json as you can see from the example below it add \ / in front of urls & for ' it turns it into &#39; is there something i can do to correct this?

Code: [Select]
if (mysqli_num_rows($r) > 0) { // Available.
 
    while ($row = mysqli_fetch_array($r, MYSQLI_ASSOC)) {
   
$results[] = array(
      'blog_id' => ($row['ID']),
          'post_date' => ($row['pd']),
'post_title' => ($row['post_title']),
'article_img' => ('http://www.socialnewsoffice.com/uploads/'.$row['article_img']),
'post_content' => ($row['post_content']),
'tags' => ($row['tags']),
'views' => ($row['views']),
'categorie_id' => ($row['categorie_id']),
'post_url' => ($row['post_url']));
    }
echo $json = Pretty_JSON(json_encode($results));

it outputs

Hey guys, I am having a bit of trouble, I am using the function time() to insert the time the form was submitted to the database.

It inserts the data like this:  1301407145

I have a date column.

I am then trying to echo the date the person submitted the form from the database using:

<?php echo date('d-M-Y h:i A', $date); ?>


the $date gets used with the mysql fetch array and for some reason it outputs it as: 01-Jan-1970 01:00 AM

Can someone explain to me why?

I am using this to insert into the db.

$date = time();
and then the $date goes into the statement.
mysql_query("INSERT INTO messages 
(reciever, sender, subject, message, date) 
VALUES
('$reciever', '$user', '$subject', '$message','$date')") or die (mysql_error());


Why isnt it working?

Sorry if this is a silly question lol.

I want to know if there is an online tool I can use to check and see what PHP code will ouput server side.

For example:

<?php
$tomorrow  = mktime(0, 0, 0, date("m")  , date("d")+1, date("Y")); ?>

I am just trying to use Associate array in another php file through session. file1.php

<?php
$age = array();
$_SESSION["age"] = array("Peter"=>"35", "Ben"=>"37", "Joe"=>"43");
foreach($_SESSION["age"] as $x => $x_value) {
echo "Key=" . $x . ", Value=" . $x_value;
echo "<br>\n";
}
?> OUTPUT: Key=Peter, Value=35
Key=Ben, Value=37
Key=Joe, Value=43 file2.php <?php
session_start();
foreach( $_SESSION["age"] as $x => $x_value) {
echo "Key=" . $x . ", Value=" . $x_value;
echo "<br>\n";
}
?> OUTPUT: PHP Notice: Undefined index: age in session.php on line 3 PHP Warning: Invalid argument supplied for foreach() in session.php on line 3   Why am I getting this error?   Above is just example I tried to demonstrate for asking question for other issue, unfortunately I got new error in this example. But actual issue was, I was trying to plot graph  using library which requires only Associate array, where the data is formed in file1.php. But I get only last index value displayed in file2.php even in graph or in echo. I don't understand why other values are not displayed in file2.php Please point me what is going wrong, Thanks.

Hi all,

Well new to the forum. And New to PHP. I have a quick question.

I'm trying to figure out what the best pratice would be to get familier with a php installation. More specificly how to discover what php is specificly producing a specific part of the final rendered HTML. I have a MyBB Forum me and my cuzin are setting up and for the life of me i can find the right place to add our own HTML to change a specific Div in the Final page output.

here is the link to our URL http://destroyrebuilduntilgodshows.net/forum/ I specificly want to find out where i can edit the contents of the "wrapper_container" Div. I have searched for the source on my local machine. but all i can find is the CSS responsible for the styling and as it turns out the images being held in that div. My end goal is to replace the "advertise here" image with come JS that does our ad managment.


So, I guess my question is How would you find it. How would you find the responsible php for that section of the HTML.



Thanks All.

Cheers

I need help debugging some homework.I have narrowed the problem down to the switch. when it gets to the switch it is spitting out the default everytime, also in the default the $score in both echo statment is not showing.

I don't know how to debug this.  The if is being executed and I want to have the else be executed.  How can I find out what $_POST['id'] is?

Code: [Select]
if (isset($_POST['id']) === false)
{
echo 'Invalid user id.';
}
else
{
partner_request($_POST['id']);
echo "A request has been sent to the user";
}

Any pointer as to why there is a fatal error?

I have a simple INSERT statement that isn't inserting anything into one of the columns: coin_name
I've gone over everything and can't figure out why. All other columns get data.
HTML form passes everything fine. Is there a good way to debug this? I've triple checked everything and there are no type-o's that I see. Driving me mad...


$query = "INSERT INTO Coin (coin_name, coin_value, coin_condition, year_minted, face_value, purchase_price) VALUES 
('$coin_name', '$coin_value', '$coin_condition', '$year_minted', '$face_value', '$purchase_price');";

I'm trying to debug a sporadic 500 error which users occasionally get when filling out form sections on my site. Whenever it happens, I try to recreate their environment and fill out the form exactly as they have done, but can never recreate the issue. I have checked my application logs for the framework I am using, but they report nothing related to the error. I'm hoping someone here might be able to help me catch this. This is where the 500 error is sometimes happening and this triggers the error which users report:

Code: [Select]
//In jquery AJAX function, which submits data to PHP form for processing
error: function(data,transport){
$.validationEngine.debug("error in ajax response: "+data.status+" "+transport)
}
Is there a way for me to try and catch what the exact error is here? The problem is I can't recreate the error, either using an AJAX call or not to call the PHP script. I need to catch the error response from the PHP script being called, but I never get an error when trying to recreate the user issue, i.e same OS/browser/form answers. The Apache error logs for the site have very little - unless I'm looking in the wrong place. I'm on CentOS, ran locate error_log and got an error_log.txt file in my vhosts directory for my site, but this just contained a 302 message log, nothing else. I also tried locate error | grep mysite.
