PHP - Steps For Troubleshooting Script

I have a page that processes a variable passed in the url to go get information out of a text file in JSON format.  For some reason though, passing one variable loads a page, passing a certain variable (who's data in the file is virtually identical to the first)  will cause the browser to just load the page indefinitely.  Maybe even more strange is that on my local machine, the variable that won't load is switched, and the other loads fine.  How can I debug what's happening when the page never loads so that I never get an error?

I am having difficulties with my include_path directives in the php.ini file. Please click the link below to see a screencast of the problem:

http://screenr.com/vhY

I am very confused as sometimes the include_path does work and sometimes it doesn't work. Also am I allowed to have multiple include_path directives or do I need to include every path in a single include_path directive.

I'm playing with this tokenizing autocomplete script but am having a strange issue with it.

It all seems to work ok and it's pulling the values over from the php file that's doing the db query ok and if you put in a value that doesn't match it will tell you so, however if you do type in a value that matches it simply disappears.

This script is exactly like the demo script except for the paths to the js, css, and php files, and I did remove the 1st example but was having this issue before removing it. No changes made to the js file, php file is identical to the demo just with my own db info and table info put in, and no changes to the css file compared to the demo.

I've tried this both with jquery 1.3.0 and 1.4.2 and have the same issue with both.

Here is the link to my test page:
http://www.erecoverydev.com/autocomplete2/autocomplete.html
Here is my js file:
http://www.erecoverydev.com/autocomplete2/jquery.tokeninput.js
Here is my php code:
Code: [Select]
<?
mysql_pconnect("localhost", "myuser", "mypass") or die("Could not connect");
mysql_select_db("mydb") or die("Could not select database");
 
$query = sprintf("SELECT cb_activities from jos_comprofiler WHERE cb_activities LIKE '%%%s%%' ORDER BY cb_activities DESC LIMIT 10", mysql_real_escape_string($_GET["q"]));
$arr = array();
$rs = mysql_query($query);

while($obj = mysql_fetch_object($rs))
{
    $arr[] = $obj;
}

echo json_encode($arr);
?>
A couple of values that are in my table are web development and kicking cats if you want to test it.

Here is the link to the demo:
http://loopj.com/tokeninput/demo.html

It just doesn't make any sense to me why the demo works and mine doesn't when they are basically identical.

Hi everyone!

I've been working on a php script to replace links that contain a query with direct links to the files they would redirect to.

Hi i have this upload script which works fine it uploads image to a specified folder and sends the the details to the database.

Hello,

I stored a fsockopen function in a separate "called.php" file, in order to run it as another thread when it needs.
The called script should return results to the "master.php" script.
I'm able to run the script to get the socket working, and I'm able to get results from the called script. I tried for hours but I can't do the twice both 

My master.php script (with socket working):

Code: [Select]
<?php
$command = "(/mnt/opt/www/called.php $_SERVER[REMOTE_ADDR] &) > /dev/null";
$result = exec($command);
echo ("result = $result\r\n");
?>

and my called.php script
Code: [Select]
#!/mnt/opt/usr/bin/php-cli -q
<?php
$device = $_SERVER['argv'][1];
$port = "8080";
$fp = fsockopen($device, $port, $errno, $errstr, 5);
fwrite($fp, "test");
fclose($fp);
echo ("normal end of the called.php script");
?>

In the master script, if I use
Code: [Select]
$command = "(/mnt/opt/www/called.php $_SERVER[REMOTE_ADDR] &) > /dev/null";
the socket works, but I have nothing in $result
(note also that I don't anderstand why the ( ... &) are needed!?)

and if I use
Code: [Select]
$command = "/mnt/opt/www/called.php $_SERVER[REMOTE_ADDR]";
I have the correct text "normal end of the called.php script" in $result but the socket connection is not performed (no errors in php logs)

Could you help me to find a way to let's work the two features correctly together?
Thank you.

hey guys im really just after a bit of help/information on 2 things (hope its in the right forum).   1. basically I'm wanting to make payments from one account to another online...like paypal does...im wondering what I would need to do to be able to do this if anyone can shine some light please?   2.as seen on google you type in a query in the search bar and it generates sentences/keywords from a database   example:   so if product "chair" was in the database whilst typing "ch" it would show "chair" for a possible match   I know it would in tale sql & json but im after a good tutorial/script of some sort.   if anyone can help with some information/sites it would be much appreciated.   Thank you

Well the subject line is pretty explicit.  I found this script that uploads a picture onto a folder on the server called images, then inserts the the path of the image on the images folder onto a VACHAR field in a database table.

The script seems to work fine because I managed to upload a picture which was successfully inserted into my images folder and into the database.
Now the problem is, I can't figure out exactly how to write the script that displays the image on an html page. I used the following script which didn't work.


Code: [Select]

//authenticate user
//Start session
session_start();

       
        //Connect to database
require ('config.php');

$sql = mysql_query("SELECT* FROM images WHERE member_id = '".$_SESSION['id']."' AND image_cartegory = 'main' ");
$row = mysql_fetch_assoc($sql);
$imagebytes = $row['image'];
header("Content-type: image/jpeg");
print $imagebytes;







Seems to me like I need to alter some variables to match the variables used in the insert script, just can't figure out which.  Can anyone help??

I have an application which runs on more than one server and need to launch one PHP script from another PHP script.  Since this is different than a function call I'm not sure how it's done.  I plan to include parameters in the URL I send and use GETs to pick up parameters in the "called" PHP script.

Thanks for sugestions

How would I go about making it to where,, I can tell the script to use a certain extension of php in the script like curl.. ?

Thanks

Hi,

I am trying to run two scripts on one page.  When I use just one script on the page they work however when I place both scripts on the same page one of them disrupts the other script.

This script prevents the other following script from working:

Code: [Select]
ini_set('display_errors', 1);
error_reporting(-1);

{
$query = "SELECT * FROM answers ORDER BY `aid` DESC LIMIT 0, 11";
}

$result = mysql_query($query);

while($row = mysql_fetch_assoc($result))

{

$answer = $row['answer'];
$aid = $row['aid'];

echo "
<div class='questionboxquestion'>
<a href= 'http://www.domain.co.uk/test/easy/answer.php?aid=$aid' class='questionlink'>$answer</a>
</div>
<div class='questionboxnotes'>
</br>
</div>
<div class='questionboxlinks'>
<div class='questionboxcategory'>
<div class='questionboxcategorytitle'>

 <a href= 'http://www.domain.co.uk/test/easy/furniture-category.php' class='questionanswerlink'></a>

</div>
</div>
";
}
Code: [Select]
    <?php if($error) echo "<span style=\"color:#ff0000;\">".$error."</span><br /><br />"; ?>
    <label for="username">Username: </label> <input type="text" name="username" value="<?php if($_POST['username']) echo $_POST['username']; ?>" /><br />
    <label for="password">Password: </label> <input type="password" name="password" value="<?php if($_POST['password']) echo $_POST['password']; ?>" /><br />
    <label for="password2">Retype Password: </label> <input type="password" name="password2" value="<?php if($_POST['password2']) echo $_POST['password2']; ?>" /><br />
    <label for="email">Email: </label> <input type="text" name="email" value="<?php if($_POST['email']) echo $_POST['email']; ?>" /><br /><br />
    <input type="submit" name="submit" value="Register" />

I cant figure out why my log out script doesnt work

all you need is

session_start();

session_destroy();

right?

here is my script to keep people loged in which works fine.


Code: [Select]
if ($_SESSION['login_time'] < strtotime('-60 minutes')) {
 
  header("Location: signup.php");
  exit();
  session_destroy();

Hi all, i'm working on a script which will allow staff members or "admins" to move users on a html table. Basically a user clicks on a cell within a table and there username is stored in a mysql database and  there username also appears in that cell and its reserved for them and other users cant take there slot. I use this for a seating plan for events.

I have made an identical table which pulls the same data from the database but is only availible to staff members but i want it so when a staff member clicks on a cell or "seat" it will ask them if they want to move themselves there or another user. Here is my code i have so far:

Above has been edited down to just show the first 12 seats.

And heres my admin_seat.php so far:

Code: [Select]
<?php
session_start();
 
/* connect to data base */
require ('../secure/connect.php');

/* get the seat number */
$seat_id = mysql_real_escape_string(trim($_GET['seat']));
 
 
 
?>
I want this script so that when i click on a seat it will ask me if i want to seat myself there, in which case it will place my username into that "seat" and remove anyone currently in that seat and reset them.

If i dont want to seat myself there i want the script to give me the option to place a user there, so i would need to list all of my registered users, ideally in a dropdown box (i will only have around 80 users tops) and then submit that and it will move that user to that seat and wipe there current seat if applicable.

something like this:

Code: [Select]
$query = "UPDATE seats_table set taken = FALSE, user_id = '0' WHERE user_id = '$user_id'";
$result = mysql_query($query) or die (mysql_error());
$query = "UPDATE seats_table set taken = TRUE, user_id = '$user_id'  WHERE id = '$seat_id'";
$result = mysql_query($query) or die (mysql_error());
the top line resets the seat back to default and availible for a user.
the third line is when a user selects a seat, it sets that seats "taken" to equal true stores there user ID and the seat ID.

any help with this would be great and also im not sure if its possible to list all of my registered users inside a dropdown box.
