PHP - Radom Image Display Fails Randomly...

If I have an array, $array, how can I loop through it (e.g. with a foreach() ) .. but just do it randomly?

So each time, random entries of the array are used and not necessarily in order.

Hello all I have a form for a meeting unable to attend log.
An attendee calls in to say they will not be able to make meeting and the form saves the reason etc into a db and infroms (via emails) all staff members who would have attended of the cancelation.

It works but for some reason the record saves twice in the db on occasion and I'm unsure why.

The loggers fills in some deatils on a form called log.php and then clicks save which goes to the following page:

Code: [Select]
<?php
$auth = $_COOKIE['auth'];
$login_id = $_COOKIE['login_id'];
header("Cache-Control:no-cache");
if(!$auth == "ok")
{ header("Location:../log_index.php");
exit();
}
include("../php_include/connection.php");
include("../php_include/functions.php");

$absent_date = $_POST['absent_date'];
$call_time = $_POST['hour'] .":". $_POST['mins'];
$reason = (! get_magic_quotes_gpc ()) ? addslashes ($_POST['reason']) : $_POST['reason'];
$reason = fix_quotes($reason);
$log_date = date ("d/m/Y");
$log_time = date("G:i");
$attendee_id = str_replace("\'","'",$_POST['attendee_id']);
$attendee_name = str_replace("\'","'",$_POST['attendee_name']);
$attendee_email = str_replace("\'","'",$_POST['attendee_email']);

Can anyone shed some light?
 Or suggest code improvements?

Hi,

I have an array of items and I randomly want to remove one from the array. What's the easiest way to go about this?

I have retrieved 5 values from a database table...
The table is such as->
tmeta_id team_id 1 1 2 2 3 3 4 4 5 5 Code: [Select]
Array (
[0] => 1
[1] => 2
[2] => 3
[3] => 4
[4] => 5 ) .. and this array I have named $nonrandom_teamno. using shuffle() I have rearranged the array, the new array being $random_teamno, which is such as the following->
Code: [Select]
Array (
[0] => 3
[1] => 4
[2] => 5
[3] => 2
[4] => 1 )I am having real problems reinserting this into the SQL tables...
I have been trying the foreach loop below...
Code: [Select]
for($i = 1; $i < (count($nonrandom_teamno)+1); $i++)
    {
        $db->query("UPDATE ancl_teammeta SET team_id ='$random_teamno[$i]' WHERE tmeta_id='$nonrandom_teamno[$i]'");       
    }It puts numbers back in the database, but not random ones. Please help me with the correct query I need!! Thank you..

I need a simple code like
Code: [Select]
$test1="1";
$test2="2";
$test=$test1|$test2;
echo $test;to randomly catch the value of strings $test1 or $test2; as each time running the code, echo shows randomly one of the strings.

Could you please guide what the third line should be ?

I'm trying to write code that will let me pull 10 out of 15 images out of a folder and display them on my site. The images are all different, and I don't want dupes to show. So far, I have the following code figured out:

---------------

$s = array ("image.jpg", "image2.jpg"); // as many images as you want
$n = rand(1,len($s)); // randomly pick a number between 1 and the
length of the array
echo "<img src='". $s[$n] .'">"; // create an image tag for the randomly selected imagine (value of the randomly defined key)
array_pop($s, $n); // This piece isn't right, it needs to EXTRACT and delete the $n array element.

// Next random image
$n = rand(1,len($s));
echo "<img src='". $s[$n] .'">";

---------------
Any ideas what array_pop should be to work properly?

Thank you for the help!

Hi there,

I'd be ever so greatful if someone could help me please. I'm really trying to get my head around working with arrays and could really do with an example in a context i fully understand.
I have made a test page for this and made a query that will search for appropriate records in my database:
  Code: [Select]
<?php $colname_Class = "3";
$colname_Ships = "-1";
if (isset($_SESSION['MM_Username'])) {
  $colname_Ships = (get_magic_quotes_gpc()) ? $_SESSION['MM_Username'] : addslashes($_SESSION['MM_Username']);
}
mysql_select_db($database_swb, $swb);
$query_Ships = sprintf("SELECT * FROM ships WHERE PlayerName = %s AND Class=%s AND Template='1'", GetSQLValueString($colname_Ships, "text"),
GetSQLValueString($colname_Class, "int"));
$Ships = mysql_query($query_Ships, $swb) or die(mysql_error());
$row_Ships = mysql_fetch_assoc($Ships);
$totalRows_Ships = mysql_num_rows($Ships);



echo $row_Ships['ShipID']; echo ' ';
echo $row_Ships['ShipName']; echo ' ';
echo $row_Ships['Class']; echo ' ';
echo '  ';
echo $totalRows_Ships = mysql_num_rows($Ships); ?>

After i made the query i echo out the ShipID, ShipName and Class from the queey which displays:

5 New Ship 3 1

So you can see the ShipID = 5, the name of the Ship is New Ship, its Class is 3 and there is only 1 record found in the database that matches the search criteria.

Lets say there are 10 records in my database... What i really need to do is  make an array of the outputted results, determine the number of records and then to randomly choose 1 of the results from the array.

Can you help me please?? If i can see an example in this context i feel i'd really learn something here.

If you can help, please do because im well stuck.

Thank you

Tom

I am working on a quiz app

image 1 shows the index.php page
image 2 shows the first question
image 3 shows the second question
image 4 shows the third question
image 5 shows the result after completing the quiz
image 6 shows the database 'quizzer' and its tables
image 7 shows the 'questions' table
image 8 shows the 'choices' table

THIS LINK CONTAIN ALL THE CODE (and images) I HAVE DONE SO FAR

https://www.mediafir...o7f5q0fe6y/quiz

1.Now my question is how to select the question RANDOMLY from 'questions' table along with 'choices' (by adding code to the existing file or create a new one).

2.If user refresh/reload the page before starting ('Start Quiz') or click 'Take Again' after finishing the quiz, the question should appear randomly.

3.Basically I want to change the order of question appearing in the browser each time I refresh.

4.My work so far is mentioned above.........Please help me with this "RANDOM" problem !!

P.S - Will it be possible, by creating a random function in PHP which will check for repeat questions in a session and check for the 'id' of the question and if it is new display it on the page.

If so what should I do and if no then how to do?

Say I have two variables like below. I basically want to select one of them, but through random choice. How do I do that?

$orange = 'Orange';
$apple = 'Apple';

 

Hey, This is my first day with PHP and I'm given an assignment by my professor. Assignment is a very basic game, all i have to do is give 2 random numbers, and add them, and check if the user has submitted the correct answer.    So i thought like this;   1-    first php file generates two random numbers 1.1- user submits the sum of those numbers   2-    second php file, gets the sum of the random generated numbers and checks if the submitted value is right.   I've come up this far;   <?php
echo "<html><head><title>calculation game!</title></head><body>";
echo "<h1>first number is</h1>";
echo (rand(100, 450));
echo "<h1>and the next number is</h1>";
echo (rand(100, 5000));
echo "<h1>now add the numbers and submit your output here!</h1>";
echo "<form name = \"myfirstform\" action  = \"formprocess.php\" method = \"PO$
echo "Enter data<br>";
echo "<input type = \"text\" name = \"firstdata\">";
echo "<br> <input type= \"submit\" value = \"Let's check!\">";
echo "</form>"; ?>      Now my problem is about; how can I keep those generated numbers and add them up. I've been digging all through the internet for syntax and php scripts, but I couldn't find an answer that helps me.    Thanks in advance.

Hey there, my problem is that I am trying to pull three images from a database and then displaying them with a large image above them. I want to then be able to click the smaller ones and then they become the larger one(kind of like on amazon). I am having 2 major problems with it at this point. the first is my while statement is only pulling 2 of the three images from the database, and secondly my image replacement javascript replaces with the smaller image. With the javascript it dosen't have to be done that way or in javascript so a link or suggestions on how to do that better would be great.

So here's my code:
<?php
include('../../php/includes/openDbConn.php');
$sku = 'c-111111';
$getImages = "SELECT * FROM Images WHERE SKU = '".$sku."'";
$resultGetImages = mysql_query($getImages);
$records = mysql_fetch_assoc($resultGetImages);
?>
   <img src="../../<?php echo $records['Path'] ?>" id="placeholder" alt="<?php echo $record['Description']; ?>" height="<?php echo $record['Width']; ?>" />
    <div id="thumbImages">
      <?php
while($records = mysql_fetch_assoc($resultGetImages)){
    echo "<a onclick=\"document.getElementById('placeholder').src='../../".$records['ThumbPath']."'\" target=\"_blank\"><img src=\"../../".$records['ThumbPath']."\" alt=\"".$records['Description']."\" height=\"".$records['ThumbWidth']."\" /></a>\n";
}
?>

and a bit on the table with the images. It stores the sku and the Path of a thumbnail, regular and large sized image. All help is much appreciated.

I have a script that uploads my images to a folder and database which works fine. I am looking to display my images on the fly to resize them. How do I intergrate my image output string with the fly string.

Current output
Code: [Select]
echo '<img src="' . $dir . '/' . $image_id . '.jpg">';

Fly string
Code: [Select]
<img src="/scripts/thumb.php?src=/images/whatever.jpg&h=150&w=150&zc=1" alt="" />

Thanks for your help

Hi im wanting to create this system where it loads all your files in a specified directory, loads all the images, although i have done that what im trying to do is have it so it prints them into a 9x9 grid automatically, in which i need to find something to restrain the echo of the variable to a limit of 9..  i need to create the <tr><th>and <td>'s automatically and also id like it so if there is more than 9, it will allow me to select a button which will load up the next section of images. heres the code i have so far:

<?php
$dir = "images/";
$dh  = opendir($dir);
while (false !== ($filename = readdir($dh))) {
    $files[] = $filename;
}

sort($files);
print_r($files); 


I then used this to try and echo into a table :S
<?php
if ($handle = opendir('images/')) {


      while (false !== ($file = readdir($handle))) {
  echo "<table width='450px' height'450px' border='4px solid #000'>";
if ($file != "." && $file != ".."){
echo "<tr><td>$file<br></td>";
echo "<td><img src=images/".$file." height='20px' width='20px'></td></tr><br>";
    }
}
echo "</table>";
closedir($handle);
}

?>

They are seperate as i havent merged together as i wud like to get them working first.

I was trying to do the max and min on the array numbers but was stuck doing that.

Any help would be greatly apprecated
Many thanks
Lewis Stevens
