PHP - Foreach Inside Of Array?

<?php

function test(){
$x = '';

$arr = array('co'=>'color','ct'=>'design','cv'=>'weight','cm'=>'hight','cp'=>'price');
foreach($arr as $k=> $v){
$x .= '<tr><td> Td '.$k.' </td><td> Td '.$v.'</td></tr>'

/* AFTER ACCESS THE ROW THAT DISPLAY "<tr><td> Td ct </td><td>Td design </td></tr>" */
/* insert HTML CODE (not by echo ) then complete the loop  */

}

return $x;
}

?>

How can I do it?

The Script:

$desired_width = 110;

if (isset($_POST['submit'])) {
    $j = 0; //Variable for indexing uploaded image

    for ($i = 0; $i < count($_FILES['file']['name']); $i++) {//loop to get individual element from the array
        $target_path = $_SERVER['DOCUMENT_ROOT'] . "/gallerysite/multiple_image_upload/uploads/"; //Declaring Path for uploaded images

        $validextensions = array("jpeg", "jpg", "png");  //Extensions which are allowed
        $ext = explode('.', basename($_FILES['file']['name'][$i]));//explode file name from dot(.) 
        $file_extension = end($ext); //store extensions in the variable

        $new_image_name = md5(uniqid()) . "." . $ext[count($ext) - 1];
		$target_path = $target_path . $new_image_name;//set the target path with a new name of image
        $j = $j + 1;//increment the number of uploaded images according to the files in array       
      
	  if (($_FILES["file"]["size"][$i] < 100000) //Approx. 100kb files can be uploaded.
                && in_array($file_extension, $validextensions)) {
            if (move_uploaded_file($_FILES['file']['tmp_name'][$i], $target_path)) {//if file moved to uploads folder
                echo $j. ').<span id="noerror">Image uploaded successfully!.</span><br/><br/>';

                $tqs = "INSERT INTO images (`original_image_name`, `image_file`, `date_created`) VALUES ('" . $_FILES['file']['name'][$i] . "', '" . $new_image_name  . "', now())";
                $tqr = mysqli_query($dbc, $tqs);

                // Select the ID numbers of the last inserted images and store them inside an array.
                // Use the implode() function on the array to have a string of the ID numbers separated by commas.
                // Store the ID numbers in the "image_file_id" column of the "thread" table.

                $tqs = "SELECT `id` FROM `images` WHERE `image_file` IN ('$new_image_name')";
                $tqr = mysqli_query($dbc, $tqs) or die(mysqli_error($dbc));

                $fetch_array = array();
                $row = mysqli_fetch_array($tqr);
                $fetch_array[] = $row['id'];


                /*
                 * This prints e.g.:
                    Array ( [0] => 542 )

                    Array ( [0] => 543 )

                    Array ( [0] => 544 )
                 */
                print_r($fetch_array);

                // Goes over to create the thumbnail images.
                $src = $target_path;
                $dest = $_SERVER['DOCUMENT_ROOT'] . "/gallerysite/multiple_image_upload/thumbs/" . $new_image_name;

                make_thumb($src, $dest, $desired_width);


            } else {//if file was not moved.
                echo $j. ').<span id="error">please try again!.</span><br/><br/>';
            }
        } else {//if file size and file type was incorrect.
            echo $j. ').<span id="error">***Invalid file Size or Type***</span><br/><br/>';
        }
    }
}

Hey, sorry that I am posting this darn image upload script again, I have this almost finished and I am not looking to ask more questions when it comes to this script specifically.   With the script above I have that part where the script should store the ID numbers (the auto_increment column of the table) of the image files inside of one array and then the "implode()" function would get used on the array and then the ID numbers would get inserted into the "image_file_id" column of the "thread" table.   As you can see at the above part the script prints the following:

                    Array ( [0] => 542 )

                    Array ( [0] => 543 )

                    Array ( [0] => 544 )

And I am looking to insert into the column of the table the following:

542, 543, 544

I thought of re-writing the whole image upload script since this happens inside the for loop, though I thought maybe I could be having this done with the script as it is right now.   Any suggestions on how to do this?

I have a table called "playlists", and a table called "musics". In the musics table, there is a column playlist_id which references the playlist that each music is contained.   I'm using api calls to display information on the site with JavaScript, so I need to return a JSON.   I need the json with the following structu   [   Playlists: [                   {                     Name: "etc",                     musics: [                                    {                                      name: "teste.mp3"
                                  },                                   {                                      name: "test2.mp3"                                    }                                  ]                      },                      ...                  ] ]   And this is my code:    $query = $con->prepare("SELECT * FROM playlists WHERE user_id = :id");

I have the following foreach statement that gets the error msg's from the array called errors. However for the last key in the array, i would not like the <br /> to be echo'd out. How can I achieve that?

Code: [Select]

foreach ($errors as $msg) {

echo $msg;

echo "<br />";

}

Hi guys,   Having trouble trying to show values from my $friend array. Only the first friend code is being displayed in my output.  There are several fields in my mysql associated with the $sql.   Any ideas?    Thanks

$sql = "SELECT * FROM friends WHERE Code = '$code' OR FriendCode = '$code' AND Status ='A'";
$result = mysqli_query($cxn,$sql)
	or die ("Can't get friends.");

$friend = array();
while($row=mysqli_fetch_array($result)) {
	if($code == $row['FriendCode']) { $friend[] = $row['Code']; }
	elseif($code == $row['Code']) { $friend[] = $row['FriendCode'];
}	
	
	foreach($friend as $key => $value) {
             echo $value.'<br />';
}

Hi,

I have an array:
Code: [Select]
Array
(
    [0] => index.php
    [1] => Home
    [2] => page.php?id=23
    [3] => Page
)

How would I loop through it so I can link the previous value to the next value within the array e.g.:

Code: [Select]
<a href="index.php">Home</a>
<a href="page.php?id=23">Page</a>
 

What I' trying to do is take my array

Code: [Select]
$stores = array("name"=>"$MktName","address"=>"$address");

And for each each value, insert it into my db
Code: [Select]
foreach($stores as $k => $v){
    mysql_query("INSERT INTO stores (name, address) VALUES('$k', '$v' ) ")
        or die(mysql_error());
}

Now, I'm just learning more about arrays, and this is obviously wrong

How do I go about getting the value of "name"? It pulls the value for "address".

Thanks in advance

I got this already, my problem is I can't get all values of my $prog array because of '=>' operator.
Is there any way to get rid of this?

Code: [Select]
foreach ($_POST['course'] as $val =>$course)
{
$prog = $_POST['program'][$val] ;
echo $course;
echo $prog;
}

I've never worked with multidimensional arrays. I have developed a calendar app. Right now i have it query the db for every day. So potentially 31 queries. Two part question: Would it be better(more "optimized") to query the db once to get all the events in that month for a certain calendar and put the rows into a multidimensional array and use php to determine which events to put in what days? And if that's the case, how do you cycle through the first key in an array like the following? I'm not even sure if this is the best way to structure the array. The number's represent the id number in the db and i will need to cycle through these.

Code: [Select]
$events = array
  (
  "1"=>array
  (
  "Bob's Birthday",
  "2011-05-24 16:30:0",
  "2011-05-25 12:00:00",
  ),
  "2"=>array
  (
   "Day Off",
  "2011-05-27 08:30:0",
  "2011-05-28 17:00:00",
  ),
  "3"=>array
  (
   "Pay rent",
  "2011-06-01 08:00:0",
  "2011-05-01 17:00:00",
  )
  );


//something like this...maybe?

foreach($events['first_key'] as $key => $value)
{
   // not a clue how to reference the contents
}

Hi everybody

I am new to arrays, and loops pretty much, so please dont be mean!

I am trying to turn a single upload form into a multiple upload form.  My logic is I need to use arrays and loop the code for uploading the data from the form to the database (for each of these files, create a thumbnail, resize and rename original, move to folder, create path, and insert all that information into the db)

But I have no idea how

I've got this in the form (now) ....
<pick an album to put the files into>
<input type="file" name="image[]" >
<input type="file" name="image[]" >

and this is the code for the whole upload. It worked for single uploads ... but I'm now at a loss ...

The code is abit messy, sorry.  I'm fairly sure I need a foreach loop, but I dont know where to put it

Really Really hoping you can help. Many thanks in advance

I am a beginner, so forgive me all to whom this is trivial...

I have an array, generated from simpleXML object, trying to parse...  The array is not symmetrical & I am having trouble finding the right code to make it work.  Help & comments are welcomed..

Here is the raw array with print_r:

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

Hello gurus,

I've been pounding my head against the wall on this one.  It must be something simple I'm missing.  I have a text field that posts ($_POST['case_ids']) a comma separated value such as 10067,10076  When I use explode to break it up it should make it an array.  However when I use it in a foreach loop I get an invalid argument error.  If I do a check for is_array() it fails the check. 

If I print the array I get:
Code: [Select]
Array ( [0] => 10067 [1] => 10076 )
So I thought maybe I get the error because the individual array elements don't have commas between them so I wrote this to put commas in between each element except the last:
Code: [Select]
$cases = array();
$numItems = count($case_ids);//get count of array
$i = 0;//initialize counter
foreach($case_ids as $key => $value){
if($i+1 != $numItems) {
$cases[$key] = $value.',';
}else{
$cases[$key] = $value;
}//end if $i+1
$i++;
}
However this new array still gets the invalid argument error.  Are these not valid arrays?

Any help would be greatly appreciated.

Thanks in advance,
Twitch

I have a simple foreach loop. The array has four rows in it. Really simple. I have confirmed the data in the array with var_dump. For some reason I cannot fathom, the loop is only processing rows 0 and 2 and is not processing 1 and 3.   Here's the code snippet:

<?php
    foreach ($postCals as $key=>$cal){
        var_dump($postCals, $cal, $key);
        echo '<td style="text-align:right;>' . $cal . "</td>";
    }
?>

$postCals has precisely 4 values. Here's the output from this part of the code (in terms of the var_dumps).   array (size=4)
0 => string '2.00000' (length=7)
1 => string '2.00000' (length=7)
2 => string '3.20000' (length=7)
3 => string '4.00000' (length=7)
string '2.00000' (length=7)
int 0
array (size=4)
0 => string '2.00000' (length=7)
1 => string '2.00000' (length=7)
2 => string '3.20000' (length=7)
3 => string '4.00000' (length=7)
string '3.20000' (length=7)
int 2   That's it. I two other foreach loops identical to this and they run fine!   Any ideas?   (misc info:   php: 5.4.7 running on XAMPP/Windows )

Hello all..

This one's sort of difficult to explain, but yet it should be a pretty simple solution..

What I'm trying to do is loop through an array that has either single event id's or a group of event id's, and run a condition on the change of id's while looping.. Sort of grouping each set if unique id's within a new event section..

Here's sort of a test code I put together:

Code: [Select]
<?php
$result = array(
array('event_id' => 70),
array('event_id' => 70),
array('event_id' => 70),
array('event_id' => 95),
array('event_id' => 96),
array('event_id' => 97),
array('event_id' => 98),
array('event_id' => 99),
array('event_id' => 145),
array('event_id' => 145),
array('event_id' => 145),
array('event_id' => 145),
array('event_id' => 166),
array('event_id' => 166),
array('event_id' => 177),
array('event_id' => 200),
array('event_id' => 200),
array('event_id' => 200)
);

$previous_id = '';
foreach($result as $row){

if ($row['event_id'] != $previous_id) {

echo '<div style="background:#ccc;">New Event</div>';

}

if ($previous_id > 0 && $row['event_id'] != $previous_id) {

echo '<table border="1"><tr><td>'.$row['event_id'].'</td></tr></table>';

$previous_id = '';

} else {

echo $row['event_id'].'<br />';

$previous_id = $row['event_id'];

}

}
?>
It's about half way working, but there are issues when the ids change and they are either single event ids in a row, or multiple same event ids in a row.. I can't think how to set the $previous_id variable properly on each loop..

Well, figured I'd throw it out there and see what happens..

Thanks..
