Display Items From A Mysql Database In A Table
I am trying to display items from a mysql database in a table but I need it to start a new table row each time multiples of 3 rows of the database table have been displayed like the following example:

Does anybody know how I can make this work using php.

Trying To Return Mysql Array Items From Function
I am writing a calendar script which returns events, holidays etc.. from MySQL for days with events. This was easy BUT then I tried to return multiple events on some days and thats where I am stuck.

I found some examples of returning arrays from functions from functions but they all use some form of array(Ƈ',ƈ',Ɖ') and then use a for loop... I am using mysql_fetch_array so this does not seem to work... First, here is some of the code from the function where I am returning the value: PHP Code:

How Do I Check If A Value Is In A Mysql Table ?

Check Contents Of Mysql Table
ok, so now that I've figured out how to allow users to upload files (with help!) I'm trying to run a script that will check the name of the uploaded file and determine if that file name already exists in a specific mysql table. Here's what I've got so far:

$filename = $_FILES['uploadfile']['name'];

$query = "SELECT * FROM $table";
$result = mysql_query($query, $conn);

while ($checkfile = mysql_fetch_assoc($results)){
$existfile = $checkfile['filename'];
}//end while

if ($existfile == $filename){
print "A file with that name already exists.";
}
else {
some script that adds the file info to $table
}

Now, this combination of while and if statements will only catch a match with an already existing filename if the already existing filename was the last one to be updated. I've tried adding the if and else statements into the while statement but then the file info gets added to the table multiple times. Does anyone have any ideas? Am I even making any sense?

How Do You Check A Table Exist In MySQL
I'm trying to check if a table in my MySQL DB exist. I have tried PHP Code:

Writing Items Back To A Table With New Numbers
I'm not an experienced php programmer but I am trying to take various items from a table that are associated with two numbers, increase one of the numbers and write the items back to the same table.

For example take a bunch of pictures that are associated with an item and version: Code:
+--------+---------+------------+
| item | version | picture |
+--------+---------+------------+
| 01 | 00 | Picture 01 |
+--------+---------+------------+
| 01 | 00 | Picture 02 |
+--------+---------+------------+
| 01 | 00 | Picture 03 |
+--------+---------+------------+
| 01 | 00 | Picture 04 |
+--------+---------+------------+

There could be any number of pictures with each version. However I would like to be able to get the pictures associated with version 00 increase the version to 01 and write the information back to the table to get the following:

Code:
+--------+---------+------------+
| item | version | picture |
+--------+---------+------------+
| 01 | 00 | Picture 01 |
+--------+---------+------------+
| 01 | 00 | Picture 02 |
+--------+---------+------------+
| 01 | 00 | Picture 03 |
+--------+---------+------------+
| 01 | 00 | Picture 04 |
+--------+---------+------------+
| 01 | 01 | Picture 01 |
+--------+---------+------------+
| 01 | 01 | Picture 02 |
+--------+---------+------------+
| 01 | 01 | Picture 03 |
+--------+---------+------------+
| 01 | 01 | Picture 04 |
+--------+---------+------------+

When I try to do this in a while loop it doesn't work. How would one go about doing this?

Comparing PHP Array From Checkbox To MySQL Table
My problem involves updating a MySQL table using checkbox input. I'm relatively new to both PHP and MySQL so I'm looking for a little direction on the smartest way to accomplish my goal.

When a user goes to a project page, they are able to categorize their project by area. The user checks a series of checkboxes and the results are stored in an arrays called $category_ids. I'll called the project id $project_id.

What I want to do is compare the array $category_ids to entries in a MySQL table for $project_id. Then I want to add the links that aren't already in the table and delete the ones that need to be deleted. The table has these fields:

projects_cat_link (table)
----------------------
category_id ¦ project_id (fields)

Does anyone have any tips on how to do this? I've gathered that maybe there's a way to get the MySQL data into a similarly formed array and then use functions like array_diff to compare. But then I'm not sure how to use the comparison in a MySQL query to add/edit/delete the links.

Putting An Array In A Mysql Database Table Field
I want to insert an array into my database but i've got a problem with it.

Before i insert the array into the dbase i check if everything is in the array with print_r($array). Everything that should be in the array is in there so i insert it into the dbase.

When i check my dbase with phpmyadmin the field that should contain my array has the word array in it so i assume the array is in the dbase. But when i retrieve the data from my dbase and check my array with print_r i get the following error: Warning: Argument to array_values() should be an array in.

How Do I Delete Items From Array?
I can add several items to the basket, but how do I delete one from the basket? I want to delete any of the added items. Here is my code for creating the array and adding items to it.

$item['price'] = "100";
$item['quantity'] = "1";

// add item
$_SESSION['basket'][] = $item;

Adding Only Unique Items To An Array
I've made a small code snippet that adds a new item ($value = $_GET) to an array in a cookie. My main question is in the title of the post, and I have a related one: How do I delete a specific value from the array and shift all the other values down to fill its place? Will this happen on its own? And one more: Using this code I display the array values in descending order;

foreach ($_COOKIE['best'] as $name => $value) {
$best = urlencode($value);
echo //insert code here
}
}

Is there any way to display this in ascending order?

Counting Items In An Array Having X Attribute
I want to randomly select 5 cards from a standard playing card deck and count how many of each suit are returned:

[connect]
$sql = "SELECT * FROM cards ORDER BY RAND()LIMIT 5";
$result = mysql_query($sql);
while($cards = mysql_fetch_array($result)) {

$value = $cards["card_value"];
$suit = $cards["card_suit"];
$image = $cards["card_image"];
--------

Using count() within the loop returns a count of 1 since each card can only be of one suit. I tried using something like this:

$spades = 0;
if($suit='spades') {
$spades = $spades+1;
}

and I tried a foreach statement to count within the loop which always returns a count of 1.

Would someone be so kind as to point me in the right direction?

Remove Items From Array, Shift Positions
Hey, lets say I have:

x = array("red", "blue", "green", "yellow", "orange", "grey");

Now lets say I have a loop that prints out what is in the array. I want to be able to remove blue green and yellow, but effectively shift down everything else in the array (in this case orange and grey) so that orange is now positioned relative to where blue was and grey is where green was. By this I mean x[1] = "blue" and x[2] now quals "grey".

How can I do this?

Adding Multiple Listbox Items To Mysql

<option value="item4">item4</option>
<option value="item5">item5</option>
</select>
"Insert into xyz set itm = '$itm'";

How To Check And Update Table?
I am trying to work out the best way to update the details in a table I have for customer data.

Each time the customer interacts with the script all the data that is used in the table is sent to the script from an external source.

What I want to do is check to see if the email address is already in the table.

If it is I want to check all the other fields and update the data.

If the email address is not in the table I want to add all the details as a new user.

I am playing with this code but I can't see to get check right to see if the email address exsists. This code always inserts a new customer into the table.

Using PHP To Sort Data In MySQL Table 1 By Values In Table 2
I have a MySQL database with 2 tables in it. products and prices.. Products has a field in it called 'prodno'. Prices has a field in it called 'prodid'.

There is one of each item in products and each product has it's own unique 'prodno'

There are multiple instances of each product's pricing in prices.. One for each price.. So if a product had multiple prices depending on quantity it would have an entry for each price.. Example:

id = 1
prodid = 7001
qty = 300
price = 12.5

id = 2
prodid = 7001
qty = 400
price = 15.5

I was wondering if I could query the database getting info from the products table but sort it according to the prices in the prices table.

Kinda like doing a "SELECT * FROM products" ordering it by the lowest price value from each item..

This is all very confusing to me, and I'm the one writing it. Let's try one last time..

Query the database selecting * from products (I plan on using all the info in products) and ordering them by the lowest price for each item in the prices table. I've tried sorting the results of just a basic SELECT * FROM products using Javascript and PHP but with pagination in the results it makes it a bit hard.

How To Check If Array Is Empty?
I am using an array named $outdata, and just wish to know how to check if the array is empty.

{
$outdata[]="You are not authorized";
}
else
{

Check Array For A String
I am trying to set up a blacklist for a service I'm making. My current objective is to call up a .txt file which contains one domain name per line. I then take the user's input from a HTTP post and check to see if it contains the domain name. Here is my current non working script:

//take user's input (example: http://www.somesite.com/files/photo.jpg)
$filename = $HTTP_POST_VARS['filename'];

//load blacklist in case of abuse
$blacklist= file('blacklist.txt');

//check submitted image against blacklisted domains
foreach($blacklist as $site){

if (strstr($filename,$site) !== FALSE) {
echo "<div><h3>This site is blacklisted</h3></div>";
exit();}}

This doesn't seem to work at all. I think it has something to do with the variable types, but I am too unfamiliar with this for Google to be a viable solution.

Check For Multiple Occurances In An Array.
I am checking an array for existence of a value, but I want to see how many times it exists in the array.

Is there a quick function to do this or must I use a loop and step through? I looked through the manual and did not see any array functions that would do this, but I may have misunderstood one of them. Which has happened before.

I was using this before I realized I had multiple occurences in the array. PHP Code:

Array To Table
is there some way i can have a script dump all the details in this array into database tables without having to type it all out manually? I'd like it in fields of gameid and gamename specified in the case clause...but short name will do if thats all i can get. All the info would be best if possible. Here is the array... PHP Code:

Mysql Check.
<?php
$sql = "SELECT * FROM songs WHERE Title = '".$_POST['songtitledelete']."' LIMIT 1";
mysql_query($sql) or die ("Couldn't execute $sql: " . mysql_error());
if (mysql_query($sql) == NULL){
echo "No such song";
} else {
$sql2 = "DELETE FROM songs WHERE Title = '".$_POST['songtitledelete']."' LIMIT 1";
mysql_query($sql2) or die ("Couldn't execute $sql: " . mysql_error());
}
?>

That should make sense? I want to check if the song is there. Otherwise it always says "Song Deleted". I want something to detect whether it's there before deleting the row.

When i run it now i dont see "No such song" when i enter an invalid song name.
