PHP - Storing Parsed Data Into A Multidimensional Array

Can anyone tell me whats wrong with this:

The file uploads fine, the url however does not get posted to the database?
I added a 'or die' but it didn't execute...Do I need to move the query higher up the script?

<?php
include ('base.php');
$id = $_GET['id'];

if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/pjpeg"))
&& ($_FILES["file"]["size"] < 20000))
  {
  if ($_FILES["file"]["error"] > 0)
    {
    echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
    }
  else
    {
    echo "Upload: " . $_FILES["file"]["name"] . "<br />";
    echo "Type: " . $_FILES["file"]["type"] . "<br />";
    echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
    echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";

    if (file_exists("upload/" . $_FILES["file"]["name"]))
      {
      echo $_FILES["file"]["name"] . " already exists. ";
      }
    else
      {
      move_uploaded_file($_FILES["file"]["tmp_name"],
      "imgs/pictures/" . $_FILES["file"]["name"]);
      echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
      }
    }
  }
else
  {
  echo "Invalid file";
  }
$file = $_FILES["file"]["name"];
 $sql = "UPDATE `chillp_security`.`staff` SET `picture` = \'imgs/pictures/$file\' WHERE `staff`.`id` = $id;";
?>

Im making a application but many users can access it at the same time, also the data that needs to be stored into the database in 3 parts firstly the user will enter some details the comany will fill out the reamining details and the user will then accept or decline the companies proposal. The issue im havign will it be easier to just store all of this information into session variables and then save them into the database at the end when all of the details are ready ?

Thank You

Hi everybody,

I generally find any assistance that I need on various sites, but this one has me stumped. I'm not overly advanced with my use of arrays, so I'd like some help here if anyone knows what I am looking for.

I have a form that I would like to submit to a MySQL database. In that form, there is the ability to add up to 3 harddrives:
Code: [Select]
Brand: <input type="text" name="hdds[0][hddbrand]" id="hddbrand"><br/>
Model and/or size,type: <input type="text" name="hdds[0][hddtype]" id="hddtype"><br/>
SN: <input type="text" name="hdds[0][hddsn]" id="hddsn"><br/>
Notes: <input type="text" name="hdds[0][hddnotes]" id="hddnotes" size="50">
Obviously the next harddrive would be hdds[1][hddbrand], etc.

I am having an awful time looping through this to get more than 1 harddrive's information, however. I've tried foreach embedded in foreach and been messing around with this for a good 3-4 hours now and I feel like I am just missing something.

I've got this right now to debug:
Code: [Select]
foreach($_POST['hdds'] as $key => $a) {
$hddbrand = $a['hddbrand'];
}
my print_r($a) comes up with the following:
Code: [Select]
Array ( [hddbrand] => Toshiba [hddtype] => Shaba 500gb [hddsn] => 5fu8bvw4 [hddnotes] =>none ) 1
Good. That's what I want. But I need some help constructing my array/loop to get the values of more than 1 drive should I have to enter information for more than 1 drive.

I feel like I am close, but I am just not getting what I need. I have not had to work with multidimensional arrays before and they are proving to be more trickier than I expected. Any help would be enormously appreciated!

I am looking at the code below:

Code: [Select]
$array = array(
                array(
                1, 2
          ),
          'a' => array(
                'b' => 1,
                'c'
        )
);       
Is this an example of a multidimensional array? If so how would I access the value of 1 from key b?

Also would the next line ('c') be automatically assigned to the asociative key of c?

I've been working on some code to:
1. Search a db for rows that have a particular "position" value
2. Search the same db for rows that have a particular "langs" value
3. Compare the two arrays resulting for 1 and 2
4. Create a multidimensional array $langsarray[langs][question id] if 3 is true.
5. For each langs array in $langsarray pick a random, non-duplicate value and add it to $qarray for a maximum of 12 elements (3 for each langs).

What I have works about 95%.

The problem is, in the first langs array, one of the 3 randomly picked values is almost always empty, and its not always the same element. Sometimes its the first, sometimes its the third, sometimes its the second...

I think I've narrowed down the issue to line 44 ($qtemp = ...). If I change the min/max values for the mt_rand function, it behaves slightly differently. Any help is much appreciated! Thanks in advance.

I need to extract data from a CSV file and insert it into a MySQL database. I am able to extract the data, however I cannot figure out how to group it.

Sample File:
01   ISBN  Name of Book   Price
02   ISBN  Name of Book   Price

So far I have an array with the entire file (reading file with PHP):

Array ([0] => 01 [1] => 12345678X [2] => Title [3] => 120.00 ...etc.

How can I modify the array to create groups of four for each item? Each item is its own array?

I am trying to store all the elements of my tree in an array.My code produces multi dimensional array, but i want it to be one dimensional. How can i get it ?

Code:-
Code: [Select]
function tree_gather($node)   //Function to calculate count
  {
    $sql = "SELECT lchild,rchild FROM tree WHERE parent = '$node'";
    $execsql = mysql_query($sql);
    $array = mysql_fetch_array($execsql);
   
    if(!empty($array['lchild']) || !empty($array['rchild']))
    {
   
      $child[] = $array['lchild'];
      $child[] = $array['rchild'];
      $child[] = tree_gather($array['lchild']);
      $child[] = tree_gather($array['rchild']);
     
    }
     return $child;
  }
Result:-
Code: [Select]

I want to store a series of data which are called in a main php file. Do you suggest to store them in xml as

file1.xml:
<title>TITLE</title>
<content>CONTENT</content>

or
file1.php:
$title="TITLE";
$content="CONTENT";


AND is it better to create separate file for each article or storing all data in one single file?

Hi,

I have a XHTML/PHP page that loads a PHP file each couple of seconds for building up the page. The PHP file should retreive data that keeps changing.

What would be the best way to store and retreive the data? Obviously i can do this with a database but that will put a lot of stress on the server as each user keeps polling the database. So i was looking into other methods of doing this.

I have tried doing this with a plain text file and CSV files using fwrite to put the initial data into a file with separators. Then retrieving that file and explode it into a multidimensional array again. I am unsuccessful here to assign the key values to the new array. I have also tried many snippets for this but these where also not working properly for me.

Maybe XML is the key, i didn't really delve into it yet but it seems i have to get extra programs or parser to actually write and change files? But then again i can't find any working tutorials on how to put multi dimensional strings back and forth between PHP and XML.

So what needs exactly to be done. Well i'm creating a game where you can fight each other with 4 units on a turn base. The units have a speed stat that determines when it's there turn to act. Like if (unit 1) has 3 speed and (unit 2) 5 speed they will move like this on the time line (unit 1) -> (unit 2) -> (unit 1) -> (unit 1) -> (unit 2). So the plan is each time the user acts with a unit to increment it's speed by the base value. A script will run each time picking up the next unit in line.

The PHP page does a check on which player the unit belongs to and if that matches the players ID it will sent the necessary information. The other player will get something like "not your turn".

Tx,

Hey

I am having a small problem with setting and storing data using $_SESSION for a login script to validate that a user is logged in.
The outputted error message I'm getting is;
Notice: Undefined index: userid ...\...\
Notice: Undefined variable: userid in ...\...\

The PHP code I'm using for the validation

Code: [Select]
<?php
session_start(); //must call session_start before using any $_SESSION variables

$username = $_POST['username'];
$password = $_POST['password'];
$userid = $_POST['userid'];

//validating a user
function validateUser()
{
    session_regenerate_id (); //this is a security measure
    $_SESSION['valid'] = 1;
    $_SESSION['userid'] = $userid;
}

Let me know if you need any other bits of code to establish what is happening I really need help with this.
Thanks.

Code: [Select]
while($row=mysql_fetch_assoc($query)) {   
   $id = $row['id'];

   $col3= $row['name3'];

 ${"$id"} = array("$col1","$col2","$col3");
    ${"$s".$i}[] = ${"$id"};
    }
This is just a brief example of what i'm trying to accomplish,$i is incremented somewhere else. I'm trying to implode the arrays in the array. So below i have imploded the main array but how do i implode the other arrays?

Code: [Select]
for($i=0;$i<11;$i++) {
$array = ${"s" . $i};
$outcomes = implode("",$array); //implodes main array

Hi freaks,

Got a simple one for ya, I THINK?

I have a multi-array that resembles this..
Code: [Select]
$_SESSION["book_array"] = array(0 => array("plantID" => $plantID, "botanicalName" => $botanicalName, "commonName" => $commonName, "use" => $use));

I would like to sort it by the botanicalName key of the inner array before I call the forech loop that renders the display so that after it renders the table the items will be seen alphabetically, code below..
Code: [Select]
<?php 
$bookOutput = "";
//$plant_use_array = '';
if (!isset($_SESSION["book_array"]) || count($_SESSION["book_array"]) < 1) {
    $bookOutput = '<tr><td colspan="4"><h6>Your Book is EMPTY!</h6></td></tr>';
} else {
// Start the For Each loop
$i = 0; 
    foreach ($_SESSION["book_array"] as $each_item) { 
$plantID = $each_item['plantID'];
$botanicalName = $each_item['botanicalName'];
$botanicalName = stripslashes($botanicalName);
$commonName = $each_item['commonName'];
$commonName = stripslashes($commonName);
$use = $each_item['use'];
//$x = $i + 1; 
// Dynamic table row assembly
$bookOutput .= "<tr>";
$bookOutput .= '<td><a href="plant_details.php?plantID=' . $plantID . '" id="bodyLink">' . $botanicalName . '</a></td>';
$bookOutput .= '<td>' . $commonName . '</td>';
$bookOutput .= '<td><strong>' . $use . '</strong></td>';
$bookOutput .= '<td><form action="book.php" method="post"><input name="removeBtn" type="submit" value="Remove"/><input name="index_to_remove" type="hidden" value="' . $i . '" /></form></td>';
$bookOutput .= '</tr>';
$i++; 
    } 
}
?>

Any help would be much appreciated!  Thanks in advance.

I am trying to write a dirty script that removes duplicate rows from a multidimensional array.

I want to be able to edit the function and spit the duplicates out to a CSV file.

Here is my test file:


$fullArray = array(array('Jim', 'Jones'),
array('Pete', 'Pumpkin'),
array('Barak', 'Obama'),
array('Jason', 'Newstead'),
array('Toby', 'Keith'),
array('Jim', 'Jones'),
array('Jim', 'Nelson'));


echo "<h1>Original</h2>";
for($i=0; $i<count($fullArray); $i++) {
echo $fullArray[$i][0] . " " . $fullArray[$i][1] . "<br />";
}

echo "<h2>Checked</h2>";
$cleanArray = array();
$cay = array();
$nn=0;
$dup=0;
// Loop the entire input array
foreach ($fullArray as $index => $item) {
echo "foreach index:$index<br>";

        // Start an internal pointer
for ($f=0; $f<count($fullArray); $f++) {
echo "for $f ";
                // if the index is lower or the same as the pointer, skip it to cut down on time
if ($f > $index) {
                        // if the rows are the same...
if($fullArray[$f][0] == $item[0] && $fullArray[$f][1] == $item[1]) {
echo "$item[0] DUP<br>";
                                // remove it from the array
$cay = array_push($cleanArray, array($item[0], $item[1]));
array_pop($fullArray[5]);

$dup++;
} else {
                                // not a duplicate
echo " not a dup<br>";
}

} else {
echo "ON THIS ONE<br>";
}
}
echo "<br><br>";
}
echo"<br>$dup duplicates found<br><br>";
print_r($fullArray);
echo "<br /><br>";
// print_r($item);
print_r($cleanArray);
?>


When I spit out the new fullArray variable, it still has an element from the duplicate record.

This is what I get for the output of the full array after the duplicate was removed:

The problem lies with the "3rd Floor" which should contain "Bonus Room" as the room.  I know that this is the only element that has no "Rooms" array, but I can't figure out how to code the trap for it.  With this data, the condition could exist anywhere, not just my example, but I am stumped with the non symmetrical array that I am unfamiliar with.  Any help?  Thanks. --akaweed
