PHP - Reservation Script

Hi Folks,

I'm creating an equipment reservation system for a client.  Every reservation has an equipmentID, ReservationDate, StartTime, EndTime.  So, basically my script searches existing records for a given date and EquipmentID.  I'm having trouble with how best to approach validation on new reservations to ensure there are no conflicts. 

Lets say two existing reservations for a given date/equipment are found.  One reservation has a startTime of 8AM and endTime of 9AM.  The second has a startTime of 12PM and endTime of 3PM.  Is there a simple way to check if the user's submitted values for StartTime and EndTime conflict with existing reservations? 

Any input would be greatly appreciated!  Thanks!

but now i am trying to instead make a modify script which is Update set so i tried to change insert to update but didnt work can someone help me out please
this my insert image script which works fine but want to change to modify instead

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

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.

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. 
Code: [Select]




<?php

//This file inserts the main image into the images table.

//address error handling

ini_set ('display_errors', 1);
error_reporting (E_ALL & ~E_NOTICE);





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

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

//Check whether the session variable id is present or not. If not, deny access.
if(!isset($_SESSION['id']) || (trim($_SESSION['id']) == '')) {
header("location: access_denied.php");
exit();
}

        else{ 







// Check to see if the type of file uploaded is a valid image type

function is_valid_type($file)

{

     // This is an array that holds all the valid image MIME types

     $valid_types = array("image/jpg", "image/jpeg", "image/bmp", "image/gif");

 

     if (in_array($file['type'], $valid_types))

         return 1;

     return 0;

}

     exit;

     header("Location: member.php");

     exit;

     $_SESSION['error'] = "Could not upload file.  Check read/write persmissions on the directory";

     header("Location: member.php");

     exit;

}







        } //End of if session variable id is not present.
 


?> 


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??

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 class='questionboxanswerlink'>
<a href= 'http://www.domain.co.uk/test/oeasy/index.php' class='questionanswerlink'>Answer</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 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
