PHP - How To Load Two Arrays In A Foreach Loop?

Hello ,
I have a table like $data[$var][$i] $data is an string, $var is a string and $i is an index int.
I am tired to write for($i=1;,$i<=count($$data[$var],$i++) { echo $data['id'][$i] ... }oouuuff
How i can make it with foreach ?
I tried foreach ($data -> $field as $value) echo $value; but i doesnt work.
Any advise ?

Hey forum,

I am a new php user and am having some issues (probably pretty basic to the likes of more experienced users), I am trying to make a script that has 4 checkboxes and a submit button, the values of the checkboxes should be passed through the array using a foreach loop, I got the basic template setup but when trying to pass the array I ran into a few problems.

If anyone would take a peek at my code and point me in the right direction it would be much appreciated.

Thanks forum.

Hey guys,

Got another question im hoping someone can help me with.

I have a foreach loop (for use in a mysql query):

   foreach ($interests as $interest) {
       $query .= "($id, $interest), ";
   }

problem is i do not want the comma(,) in the last loop.

Is there some kinda of function i can use so it does not insert it on last loop?

Or should i just use a for loop with a nested if loop? something like ;

   for($i=0; $i < count($interests); $i++){
      $query .=
      "($id, '$interests[$i]')";
      if($i + 1 < count($interests)) {
         $query .= ", ";
      }
      }


Cheers guys

what im trying to do is echo all of the results from the database query but add bold to results with a pid of 0. here is my code:


$list = '';
$query = $link->query("SELECT * FROM ".TBL_PREFIX."forums
                        ORDER BY f_lid ASC");
$result = $query->fetchAll();

foreach($result as $key => $val)
{
    if($result[$key]['f_pid'] == 0)
    {
        $list .= '<b>'.$result[$key]['f_name'].'</b><br />';
    }
    $list .= $result[$key]['f_name'].'<br />';
}
echo $list;


this works fine but the ones with a pid of 0 are displayed twice. once as bold and then once normal like so:

my question is how to prevent this.

how do I echo "blah" after the first loop in a foreach loop and the in the rest of them echo "crazy"?

I am working on a photo gallery script in which I need to show 9 images at a time.

Here is my script so far

Code: [Select]
<?php foreach($pictures->result() as $p): ?>
<?php for($i = 1; $i <= 9; $i++) { ?>
    <div class="item">
     <ul>
      <li><a href="images/gallery/<?=$p->category;?>/<?=$p->photo_name;?>" rel="example1" ><img src="images/gallery/<?=$p->category;?>/thumb_<?=$p->photo_name;?>" alt="#" /></a></li>
     </ul>
    </div><!-- end item -->
<?php } ?>
<?php endforeach; ?>

At the moment the script is showing one image at a time 9 times and for every entry in my database.

I have been battling this for a little while now. Thanks in advance for all of your help!

Hey guys, need help on some addition.




foreach($login as $line_num => $line)
{
  $login = explode(" ", htmlspecialchars(str_replace(" "," ",$line)));
  if(stristr($login[1], "\n")) $login[1] = substr($login[1], 0, strlen($login[1])-2);
  $account_data[$line_num] = array($login[0], $login[1]);
$UserID = $login[0];
$AuthKey = $login[1];
$MobLink = "http://mobsters-fb-apache-dynamic-lb.playdom.com/mob_fb/";
$RefreshStat = file_get_contents($MobLink."refresh_stat_manual?user_id=".$UserID."&auth_key=".$AuthKey);
$Cash = explode ("<cash>", $RefreshStat);
$Cash = explode ("<", $Cash[1]);
$Cash = $Cash[0];
$CashForEcho = "$".number_format($Cash[0]);
echo $CashForEcho."<br/>";
echo "<br/><br/>";
}




The variable $Cash will be dynamic for each user I put in the $login_file, and I need to add all of those values up. So say I put in 3 users within the $login_file, and the $Cash for user 1 was $3,000, the $cash for user 2 was $6,000 and the $cash for user 3 was $1,000, I want to be able to automatically add them all up, so it would echo '$10,000' at the end. Hope I've explained it for you guys to understand easily enough, if not let me know.

Thanks

I have a foreach loop which shows the breadcrumb display. But it's stopped working. For some reason the links are no longer links. They are just echoed on screen with no <a> tags.

setting up array:

$crumb_query = mysqli_query($link, "SELECT 
f.forum_id, f.forum_cat_id, f.forum_name,
c.cat_id, c.cat_name
FROM ".TBL_PREFIX."forums as f
LEFT JOIN ".TBL_PREFIX."categories as c
ON c.cat_id = f.forum_cat_id
WHERE f.forum_id = '$forum_id'
") or die(mysqli_error($link));

$crumb_info = mysqli_fetch_array($crumb_query, MYSQLI_ASSOC);

$crumbs = array("index.php" => "Board Index",
"./view_category.php?cid={$crumb_info['cat_id']}" => $crumb_info['cat_name'],
"./view_topics.php?fid=$forum_id" => $crumb_info['forum_name']);

echo build_crumbs($crumbs);


the function:


function build_crumbs($crumbs)
{

foreach($crumbs as $key => $value)
{
$crumb_display = "<a href=\"{$key}\">{$value}</a>";
$crumb_display = implode(" - ", $crumbs);
}

return $crumb_display;
}


can anyone see where im going wrong?

For some reason I'm getting an invalid argument supplied for foreach error and I'm not sure why.

Does anybody know how to make the following code correct? real sorry but its just absolutely blowing my mind im awful with loops and have pretty much no clue what the hell im doing in honesty, any help would be great, Thanks

Code: [Select]
$addIDs_ary = array_map('intval', $_POST['chkInv']);
$addIDs_ary = array_filter($addIDs_ary);
$value = $addIDs_ary;
//Check if hit_id is already in hitlist
$query = mysql_query("SELECT * FROM hitlist WHERE player_id  = '$playerID'");
$result = mysql_query($query);
while ($result = mysql_fetch_assoc($result))
foreach ($result as $hit_id => $value){
if($result[$hit_id] == $value);
$str = "";
}
}
else

Hello. 

I was wondering if anyone could please help with a problem I seem to be having a problem with my foreach loops. I have an array that holds other arrays. When I am trying to populate the database tables with the information in each array, things are going horribly wrong.

This is my code:

$tabledata = $this->db->get('tableinfo');

$i = 0;
$_temp = array();
foreach($tabledata->result() as $row) {
	$data[$i] = $this->callAPI("lateststandings&records=3&category=" . $row->category . "&distance=" . $row->distance_id);
	array_push($_temp, $row->dbname);
	$i++;
}

$j = 0;
foreach($data[$j]['Records']['Record'] as $record) {
	$record['FirstName'] .= " " . $record['LastName'];
	$this->db->replace($_temp[$j], $record);
	$j++;
}

 

When this is run 2 things are happening:

1) What I am expecting to happen is, there should be 3 rows added to each table. But only 1 is being added to each table.
2) The 3 rows that are being created (1 in each table), are the 3 rows I am expecting to see in the first table.

I am not sure what I am doing wrong in these loops.

 

ok.

say i have a list with a foreach loop in it.
like this:

Code: [Select]
echo'
<ul>';

$link = Link::find_all();
foreach($link as $links){
$name = $links->name;

echo'
<li>'.$name.'</li>';

}
echo'
</ul>';




now.
say that i want to put this part :
Code: [Select]
$link = Link::find_all();
foreach($link as $links){
$name = $links->name;

into a function so i can reuse the code...

like this:

FUNCTION
Code: [Select]
function(find_li){
  $link = Link::find_all();
  foreach($link as $links){
  $name = $links->name;
}
Code: [Select]
echo'
<ul>';

find_li();

echo'
<li>'.$name.'</li>';
}
echo'
</ul>';


the problem is the foreach } its not inside the function so the function will not work. but it needs to be after the </li> so that i get all the results in the <li>

so is there a way to put the function before the <li> and the } after the </li>

Hello to all

I have problem a with my foreach loop..

First : Is it possible to rename each element that's been outputted  everytime the loop execute?
Code: [Select]
<?php
$arr = array(mikel, 17, cambodia, 50kgs, 5 feet, anna, 21, peru, 45kgs, 6 feet);
foreach ($arr as &$value) {
    $value = $value;
}
?>
What i would like on the result of the foreach loop is
name : mikel
Age : 17
address : cambodia
weight : 50kgs
height : 5 feet
is this possible?

Second : i want to echo the result of the for each loop in every 5 turns.
result 1 = mikel, 17, cambodia, 50kgs, 5 feet
result 2 = anna, 21, peru, 45kgs, 6 feet

Can anyone help me on this? thanks

foreach ($export as $group => $arrayOpts) 
{
//echo $arrayOpts[0]["choice"]; This returns No
/**
  * If the option hasn't been selected, leave that part out entirely
 **/
if (!empty($arrayOpts)) // if the entire options array isn't empty, we'll display
{
   if ($arrayOpts[0]["choice"]!="0" || $arrayOpts[0]["choice"]!="No")
   {
$pdf->Cell(40,10,$group,0,1); 
$pdf->ImprovedTable($header,$arrayOpts);
$pdf->Ln();
   }
}
}

Unfortunately I can't show print_r's at the moment, the main issue is it's running those $pdf-> lines even if that variable is equal to No, I proved it because up above commented out returns No, but it still runs the pdf code.

Any thoughts? Been staring at it a while, maybe it's something in my conditional statement? Thanks.

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
