PHP - Can I Put A Foreach Loop In A Function Before An <li> And The } After The </li>

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!

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.

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

Code: [Select]
<?php

// Include the database page
require ('../inc/dbconfig.php');

if (isset($_POST['edit_event_lineup'])) {
    $event_items = $_POST['event_items'];
    $event_id = (int)$_POST['event_id'];
    
    foreach ($event_items as $items) { 
        print_r($items);
        $segment_writer_id = (int)$_POST['segment_writer_id'];
        $introduction = mysqli_real_escape_string($dbc, $_POST['introduction']);
        $conclusion = mysqli_real_escape_string($dbc, $_POST['conclusion']);
        $segment_type = mysqli_real_escape_string($dbc, $_POST['segment_type']);
        $match_number = (int)$_POST['match_number'];
        $segment_number = (int)$_POST['segment_number'];
        $match_type_id = (int)$_POST['match_type_id'];
        $segment_title = mysqli_real_escape_string($dbc, $_POST['segment_title']);
        $match_type_id = mysqli_real_escape_string($dbc, $_POST['match_type_id']);
        $titles_id_list = mysqli_real_escape_string($dbc, $_POST['titles_id_list']);
        $stipulations_id_list = mysqli_real_escape_string($dbc, $_POST['stipulations_id_list']);
        $characters_id_list = mysqli_real_escape_string($dbc, $_POST['character_id_list']);
        $preview = mysqli_real_escape_string($dbc, $_POST['preview']);
    }

    $query = "INSERT INTO `event_segments` 
            (event_id, segment_writer_id, segment_type, sort_order_preview, segment_title, preview, is_submitted_yes_or_no_id) 
        VALUES 
            ('".$event_id."', '".$match_writer_id."', '".$segment_type."' ,'".$sort_order_preview."','".$segment_title."','".$preview."',2)";
    mysqli_query($dbc, $query);
    
}
        
?>

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

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?

hello.

i have a foreach loop thats pulling out information that i dont want. how do i stop it.

this is the loop


Code: [Select]
      //GET THE TEXT
$PCa = PageContent::find_by_pageContID($PCidA);
foreach ($PCa as $PCas){
$title = $PCas->title;
$link = $PCas->link;


echo $title;
echo "<br/>";
}

the loop sits inside this function which has more loops

Code: [Select]
function listNavText($PHGlidA, $PHLobA, $PHLodA){
//GET THE LANGUAGE
$langBS = basicSettings::find_by_id(1);
$langID = $langBS->language_id;

//GET THE LIST ORDER
$PHLoa = PhLists::find_by_order($PHGlidA, $PHLobA, $PHLodA);
foreach ($PHLoa as $PHLoas){
$PHLidA = $PHLoas->id;

                            //GET THE LIST TEXT IDS
$PCba = PCbridge::find_by_list($PHLidA, $langID);
foreach ($PCba as $PCbas){
echo $PCidA = $PCbas->pageContent_id;

                                      //GET THE TEXT
$PCa = PageContent::find_by_pageContID($PCidA);
foreach ($PCa as $PCas){
$title = $PCas->title;
$link = $PCas->link;


echo $title;
echo "<br/>";
}
}
}
}


this is what it echoes out


105L1-Title1
118
116
114
112
110
108L2-Title4
111
109L2-Title5
113
115
117
106L1-Title2
119
107L1-Title3


the number at the start is the text id

L1-Title1 to L1-Title5 are tiles ($title)
the spaces are links ($links)


the problem is that i don't want the link spaces showing. just the 5 titles



thanks

I am using a foreach loop to get the results of an array. My problem is that I need the results combined into one string. How can I accomplish this?

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

Put its only echoing out 3, not the whole array.

Hi everyone, greetings from Brazil. I am an average php coder, much more a designer than an programer, and i am in a looper trouble.. Can anyone try to help me?   Here is my code:               <table border="1">

Object-  Take array of IP addresses and add up all occurrences of a particular IP address. 



//$item is an array of IP addresses

foreach ($item as $key => $unique_ip)
{
         if($unique_ip == $ip) 
                                                 $a++;
}
echo $a;

I get a blank page.  What am I missing?

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.

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

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.

 

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
