PHP - Join Mysql Tables, Echo Data Based On Different Tables

so I'm trying to change some specific columns in a row in a table of a MySQL database by calling the Doctrine_Query when an option is selected inside an admin panel of my website.

Here are the details:

Table name: chatUsers
I need to find all rows with the person who has a username of: $chatUsers->username (The column inside chatUsers is called username) Once all those rows are found, change the value of all the row's column "type" to "user" Is this even possible?

So far I have:
[/list] Code: [Select]
<?php
function userChatReset(){
     $query = Doctrine_Query::create()->update('db_chatUsers')->set('type', 'user')->where('username = '.$chatUsers->username);

          //execute query
$rows = $query->execute();
echo $rows.' rows updated';
}
?>

...And I'm not sure where to go from there, or if that's even correct. Sorry in advance, I'm not very good with PHP yet.

Guys, quick one.

Im writing a script for a form to post info into a MySql table.

Now rather than just having a single row for input I'd like to have lets say 10 rows, so I can add 10 records to the database.

What I'm pondering is 2 things:

1: can i just repeat
  Code: [Select]
<input type="text" name="opponent" size="27" />
over and over, or is it going to need its own name each time for example;
Code: [Select]
<input type="text" name="opponent2" size="27" />
<input type="text" name="opponent3" size="27" />

2: when it comes to the processing script is it more economical to have the forms input field named the same over and over (if it IS possible) and if not whats the most econimcal way to code my
Code: [Select]
$opp= $_POST['opponent'];
$query="INSERT INTO fixtures (match_date, season, opponent) VALUES ('$date', '$season', '$opp',)";


Your help and comments are appreciated as always guys

I have the following code, and really can't see what is wrong with it. Any help would be great.

<?php
if (!mysql_connect('127.0.0.1', 'root', '')) {
echo 'Could not connect to mysql';
exit;
}

$dbname = 'Requests';
$result = mysql_list_tables($dbname);
if (!$result) {
echo "DB Error, could not list tables\n";
echo 'MySQL Error: ' . mysql_error();
exit;
}

while($row2 = mysql_fetch_row($result)) {
   foreach ($row2[0] as $table_id) {
      
$query = "SELECT * FROM $table_id";
$dbresult = mysql_query($query);

// added code to use the tablename and select all records from that table
// create a new XML document
$doc = new DomDocument('1.0');
// create root node
$root = $doc->createElement('mixes');
$root = $doc->appendChild($root);
// process one row at a time
while($row = mysql_fetch_assoc($dbresult)) {
     // add node for each row
  $occ = $doc->createElement($table_id);
  $occ = $root->appendChild($occ);
   // add a child node for each field
  foreach ($row as $fieldname => $fieldvalue) {
       $child = $doc->createElement($fieldname);
    $child = $occ->appendChild($child);
   $value = $doc->createTextNode($fieldvalue);
    $value = $child->appendChild($value);
     } // foreach
} // while
}
}


echo 'Wrote: ' . $doc->save("s.xml") . ' bytes'; // Wrote: 72 bytes

Hi all

I have 3 tables
Table_1, Table_2 and Table_3

Table_1 is a list of countries, with name and country_id
Table_2 is a table that has 3 fields, id, name and description
Table 3 is a table that has name, Table_2_id

So what I need to do:
Display the name and description field of Table_2 in a form
Loop through the countries table and display each as an input box and display on the same form
When I fill out the form details, the name/description must be inserted into Table_2, creating an id
The input boxes data then also needs inserting into Table_3, with the foreign key of Table_2_id

So a small example would be:
Name: testing
Description:  this is a test
Country of Australia: Hello
Country of Zimbabwe: Welcome

This means that in Table_2, I will have the following:
=============================
| id   | name    | description
| 1    |  testing | this is a test
=============================

Table_3
=============================
| Table_2_id |  name         | country_id
| 1                    | Hello          | 20
| 1                    | Welcome  | 17
=============================

20 is the country_id of Australia
17 is the country_id of Zimbabwe

Code:

Generating the input fields dynamically:

                           $site_id = $this->settings['site_id'];

                           $options = '';
                           $country_code = '';
   $query = $DB->query("SELECT country_code, country_id, IF(country_code = '".$country_code."', '', '') AS sel FROM Table_1 WHERE site_id='".$this->settings['site_id']."' ORDER BY country_name ASC");
   
                               foreach ($query->result as $row)
                               {
                                        $options .= '<label>' . 'Test for ' . $this->settings['countries'][$row['country_code']] . '</label>' . '<br />';
                                        //$row['country_id'] is the country_id from Table_1
                                        $options .= '<input style="width: 100%; height: 5%;" id="country_data" type="text"  name="' . $row['country_id'] . '"  value="GET_VALUE_FROM_DB" />' . '<br /><br />';
                               }
                              echo $options;


This outputs:
Code: [Select]
Textareas go here......
<label>Test for Australia</label>
<input type="text" value="" name="20" id="country_data" style="width: 100%; height: 5%;">
<label>Test for Zimbabwe</label>
<input type="text" value="" name="17" id="country_data" style="width: 100%; height: 5%;">

Now, I need to insert the value of the input field and it's country_id (20 or 17) into Table_3 and also Table_2_id.
This then means I could get the value from Table_3 to populate 'GET_VALUE_FROM_DB'

But I'm at a loss on how I'd do this.

Could someone help me with this?

Thanks

Hello, I'm trying to get a join with 2 tables but cannot get it to work. It's a contentsystem with an ID for the author. Another table tells the name of the author. Now I want to join these things. This is what i've coded so far:

<?
$query = "SELECT rmnl_content.content_aid, COUNT(rmnl_content.content_id), rmnl_crew.crew_id, rmnl_crew.crew_name

FROM rmnl_content, rmnl_crew" "where rmnl_content.content_aid = rmnl_crew.crew_id";
   
$result = mysql_query($query) or die(mysql_error());

// Print out result
while($row = mysql_fetch_array($result)){
   echo " <b>". $row['COUNT(rmnl_content.content_id)'] ."</b> posted messages by ". $row

['crew_rmnl.crew_name'] ."</td> .";
   echo "<br />";
}
?>

I have two tables book and category,    book

id   title           author   category          isbn
1    fun times       Joe         1              16161514 (new record)
2    fishing trip    Jim      Juvenile Science  88771615 (old record) 
3    beach hunt      Sam         3              81009991 (new record)
4    day out         John        3              81009991 (new record)
5    farm fun        Jim      Classic Kids      88771615 (old record)

category

id   cat_name
1    horror 
2    science
3    kids 

I use the join query below to display a list of all book info, works fine.

SELECT b.id, b.title, b.category, b.author, b.isbn, b.publicationYear
        c.cat_name
        FROM book AS b
        INNER JOIN category AS c ON b.category = c.id

The problem I am facing is that all some of the books (1000's actually) in the db have been imported from a previous db, and instead of containing an integer for the category they contain a string such as 'General Fiction' or 'Popular Classics' etc.    Must I import all of these categories into the 'category' table and assign an integer to them, or is there a way of simply displaying the string that is contained within the 'book' table as it stands?   I use the code below to display the html table of results;

while($row = $res->fetch_array()) {
    echo '<tr>';
    echo '<td>' . $row['id'] . '</td>';
    echo '<td>' . $row['title'] . '</td>';
    echo '<td>' . $row['author'] . '</td>';
    echo '<td>' . $row['cat_name'] . '</td>';
    echo '<td>' . $row['isbn'] . '</td>';
    echo '<td>' . $row['publicationYear'] . '</td>';
    echo '</tr>';
    echo '</tbody>';    
};

How do I join these queries and is it best practice?

$e_query = mysql_query("SELECT `employeeid`, `userid`, `companyid`, `function`, `timestamp` FROM `employees` WHERE `companyid` = '${c_row['companyid']}'");

$e_row = mysql_fetch_assoc($e_query);
         
$u_query = mysql_query("SELECT `id`, `firstname`, `lastname`, `username`, `accounttype` FROM `users` WHERE `id` = '${e_row['userid']}'");

$u_row = mysql_fetch_assoc($u_query);
         
$eQ = "SELECT `capitalrequested` FROM `eQuestions` WHERE `userid` = '${u_row['id']}'";
         
$eQRes = mysql_query($eQ);
         
$reQ = mysql_fetch_assoc($eQRes);
         
$iQ = "SELECT `capitalavailable` FROM `iQuestions` WHERE `userid` = '${u_row['id']}'";
         
$iQRes = mysql_query($iQ);
         
$riQ = mysql_fetch_assoc($iQRes);

Alright this is going to be a doozy:

I have 3 tables: Collectibles, CollectiblesMethods and CollectionsCollectibles

Collectibles contains: ID, Photo, Collectible, Value, Resale, Rarity
CollectiblesMethods contains: ID, Collectible, Method
CollectionsCollectibles contains: ID, Collectible, Collection, Amount

Needless to say, this is a many to many relationship model. (many methods to one collectible, many collectibles to one collection).

The page collectibles.php is contained inside collspec.php

collspec.php shows information relating to a specific collection called by GET.
collectibles.php shows all collectibles belonging to the same specfic collection in collpec.php, thus why it is contained inside it.

I want collectibles.php to output the following:
Photo, Collectible, Amount, Resale, Rarity, Method

I already have collectibles.php outputting:
Photo, Collectible, Amount, Resale, Rarity

Method is proving to be difficult. I can either get it to show the word None for every collectible with this code:
<table width="99%">
<tr>
<th colspan="6"><h2>Collectibles</h2></th>
</tr>
<tr>
<td>Photo</td>
<td>Name</td>
<td># Needed</td>
<td>Sells For</td>
<td>Rarity</td>
<td>Obtained</td>
</tr>
<?php 
$sql2 = "SELECT * FROM CollectionsCollectibles LEFT JOIN Collectibles ON CollectionsCollectibles.Collectible = Collectibles.Collectible WHERE Collection = '" . mysql_real_escape_string($item) . "'";
$collectible = mysql_query($sql2);
if (trim($row['Collectible']) != '') 
while($row2 = mysql_fetch_array($collectible)){
?>
<tr>
<td width="14%" valign="top"><img src="<?php echo "$img{$row2['Photo']}"; ?>"></td>
<td><?php echo $row2['Collectible']; ?></td>
<td><?php echo $row2['Amount']; ?></td>
<td><?php echo $row2['Sell']; ?></td>
<td><?php echo $row2['Rarity']; ?></td>
<td>
<?php
$sql3 = "SELECT CollectiblesMethods.Method FROM CollectiblesMethods WHERE Collectible = '" . $row2['Collectible'] . "'";
$obtain = mysql_query($sql3);
if (trim($row['Method']) != '') 
while($row3 = mysql_fetch_array($obtain)){
?>
<tr>
<td><?php echo $row3['Method']; ?></td>
</tr>
<?php
} else 
  echo 'None';
?>
</td>
<?php
} else 
  echo 'None';
?>
</tr>
</table>

or I can get it to show the Methods (of which certain collectibles have more than one method) using this code but with a catch; it repeats the photo, name, value and resale if there is more than one method for a given collectible:
<table width="99%">
<tr>
<th colspan="6"><h2>Collectibles</h2></th>
</tr>
<tr>
<td>Photo</td>
<td>Name</td>
<td># Needed</td>
<td>Sells For</td>
<td>Rarity</td>
<td>Obtained</td>
</tr>
<?php 
$sql2 = "SELECT * FROM CollectionsCollectibles LEFT JOIN Collectibles ON CollectionsCollectibles.Collectible = Collectibles.Collectible LEFT JOIN CollectiblesMethods ON Collectibles.Collectible = CollectiblesMethods.Collectible WHERE Collection = '" . mysql_real_escape_string($item) . "'";
$collectible = mysql_query($sql2);
if (trim($row['Collectible']) != '') 
while($row2 = mysql_fetch_array($collectible)){
?>
<tr>
<td width="14%" valign="top"><img src="<?php echo "$img{$row2['Photo']}"; ?>"></td>
<td><?php echo $row2['Collectible']; ?></td>
<td><?php echo $row2['Amount']; ?></td>
<td><?php echo $row2['Sell']; ?></td>
<td><?php echo $row2['Rarity']; ?></td>
<td><?php echo $row2['Method']; ?></td>
<?php
} else 
  echo 'None';
?>
</tr>
</table>

So Let's say I have a collection called Toys. This is how it outputs using my above codes:

1st Code example:
__________________________________________
|Photo|Name |Amount|Sells For   |Rarity       |Obtained|
|Pic1  |Marble| x5        | 20 cents | Common | None     |
|Pic2  |Train   | x1       | 5 $          | Rare       |  None    |

2nd Code example:
__________________________________________
|Photo|Name |Amount|Sells For   |Rarity       |Obtained|
|Pic1  |Marble| x5        | 20 cents | Common | Barter   |
|Pic1  |Marble| x5        | 20 cents | Common | Trade    |
|Pic2  |Train   | x1       | 5 $          | Rare       |  Gift      |

How it should output:
__________________________________________
|Photo|Name |Amount|Sells For   |Rarity       |Obtained|
|Pic1  |Marble| x5        | 20 cents | Common | Barter   |
|        |          |             |               |               | Trade    |
|Pic2  |Train   | x1       | 5 $          | Rare       |  Gift      |

As you can see, I want it to output all methods obtained in the same box, increasing the rowspan as necessary.

I don't want it to output None (since this is not true) as in the first example.
I don't want it to repeat the same information simply to add a line for the next method as in the second example.

Can someone help me figure out what I'm doing wrong?

Hi guys! Once again i require your endless talents!

I have 2 tables in my mysql DB. One table is a list of products a store offers, the other is the cart of the user. I need to find the most efficient way or retrieving the images and prices from the LIST OF PRODUCTS table based on the list of PRODUCT NUMBERS stored in the cart table of the user.

List of products offered

*************************
Prod # * Price *      img src     *
*************************
001     * 19.99* imgs/pic1.jpg *
002    * 29.99 * imgs/pic2.jpg *
*************************

User's Cart
*********************
Prod # * quantity * size *
*********************
001     *    10       *  m    *
002     *     4        *  s     *
********************

Basically i just want to retrieve ONLY the rows that i need (ones that the user has added to his/her cart) and ASSOCIATE the img src with the quantity and size so that i can lay it out in a table on a view_cart page...

If you want a good laugh just take a look at what ive done so far...

Code: [Select]
$cart = mysql_query("SELECT * FROM ".$session."");

$cart_row_count = mysql_fetch_assoc($cart);
$cart_row_count = mysql_num_rows($cart_row_count);

if($cart_row_count != 0){

$i = 1;

while($cart_result = mysql_fetch_assoc($cart)){
${"product$i"} = $cart_result['product'];
${"size$i"} = $cart_result['size'];
$i++;
}

$i2 = 1;

$query = "product = ".${"$product$i2"}." ";

while($i2 <= $i){
$i2++;
$query .= "AND ".${"$product$i2"}." ";
}
}
