PHP - Need Help Returning A Value From A Foreach Loop

When using cURL, how would I be able to include a call inside my get_all that basically will loop through all the next_page, get and store the data and then output it to $response->data when the "next_page" parameter becomes null?

**Here is the method**:

    public function get_all()
    {
        return $response->data;
    }

**This is what $response->data is returning as of now** (The cURL code wasn't included here):

    "paginator": {
        "total": 3092,
        "per_page": 500,
        "current_page": 2,
        "last_page": 7,
        "prev_page": "https://oc.com/api/v1/employees/?page=1",
        "next_page": "https://oc.com/api/v1/employees/?page=3"
    },
    "data": [
            {
                "id": 1592,
            etc....

Here are all of my unsuccessful attempts:

        public function get_all()
        {
    
    //        $next_url = $response->paginator->next_page;
    //
    //        foreach ($response as $next => $next_page) {
    //            print_r2($next);
    //
    //            if ($next_url !== null) {
    //                $next_page = $response->data;
    //            }
    //        }
    
    //        foreach ($response as $paginator => $next_page) {
    //            if ($next_url !== null) {
    //                $return[] = $response->data;
    //            }
    //        }
    
    //        var_dump($response->paginator);
    
    //        if ($next_url !== null) {
    //            $this->get_all($path, $args, $next_url);
    //        }
    
            return $response->data;
        }

this is only returning one record, when I know there are more, and it's an endless loop crashing my browser, can someone tell me how my brackets are wrong, or what is wrong?

Code: [Select]
if (isset($_POST['search'])){
$keyword=$_POST['keyword'];
}
$sql="SELECT id, fname, lname FROM obituaries WHERE lname LIKE '%$keyword%' OR fname LIKE '%$keyword%' ORDER BY id DESC";
$results = mysql_query($sql);
$num = mysql_num_rows ($results);

if ($num > 0 ) {
$i=0;
while ($i < $num) {
$id = mysql_result($results,$i,"id");
$fname = mysql_result($results,$i,"fname");
$lname = mysql_result($results,$i,"lname");

 ?>
<a href="view.php?id=<?php echo ($id); ?>"><?php echo($fname); ?> <?php echo($lname); ?></a>
<?php
          }
}

?>Thanks in advance

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

Hello all,  I'm new to PHP and new to this forum (although I have benefitted from your help already -cheers!). However,  this time I cannot find the answer I need/recognise/understand..

I have a form and want to conduct tests on each field returning an error message as a session variable if the test fails. The test will be different for some of the fields, and the error message is specific to each field. If there is an error in any one of the fields I want to be redirected to a failure page where all of the error messages are displayed,  otherwise I am sent on to another page.

I have already written and tested a function to sanitise the incoming form data,  so that's not a problem - it's just how to loop through and test.

I can guess that there are many ways to do this but I need to understand why one option is better than another,  and follow the syntax used (it's all part of my steep learning curve)

The approach I have thought to use is to create an array holding the field name, the test and the message,  then loop through using foreach, applying the array values into the test and creating the error message....but it's not working for me.

The other method is to declare a variable $Stop='No' and if the loop identifies an error, part of the output is to change this to 'yes' and through that redirect to the error page.

I'd really welcome your advice and tuition....cheers.. my code so far is...

Code: [Select]
$Stop='No';
$StaffPassCheck=sanitisealphanum($_POST['PasswordCheck']);

$Errors[0]['value']= sanitisealphanum($_POST['FirstName']);
$Errors[0]['message']='Please re-enter your name';
$Errors[0]['test']=($StaffFname="");

$Errors[1]['value']= sanitisealphanum($_POST['Surname']);
$Errors[1]['message']='Please re-enter your surname';
$Errors[1]['test']=($StaffSname="");

$Errors[2]['value']= sanitisealphanum($_POST['Post']);
$Errors[2]['message']='You must select an option';
$Errors[2]['test']=($StaffPost="Select Value");

$Errors[3]['value']= sanitisealphanum($_POST['Username']);
$Errors[3]['message']='You must select an option';
$Errors[3]['test']=($StaffUser="");

$Errors[4]['value']= sanitisealphanum($_POST['Password']);
$Errors[4]['message']='Please re-enter your password';
$Errors[4]['test']=($StaffPass="");

$Errors[5]['value']= sanitisealphanum($_POST['PasswordCheck']);
$Errors[5]['message']='Sorry, your passwords do not match';
$Errors[5]['test']=($StaffPass===$StaffPassCheck);

foreach ($Errors as $key => $Value){
if ( $Errors['test']=true ){
$Stop='Yes';
return $_SESSION[$key]=$Value['message'];
}
}

if ($Stop='Yes'){
header('Location.test.php');
die();
}else{
header('Location.indexp.php');
}

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 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

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

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?

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"?

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

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>

I guess I'll rephrase since my wording wasn't very clear. Why don't

echo "<p>\n";
if (!empty($locations) && is_array($locations)) {
  foreach ($locations as $field => $val) {
  if ($field == "City") {
     echo $field  . ' : ' . $val . "<br />\n";
        $val = $cityvar;
}
  if ($field == "ZipPostalCode") {
     echo $field . ' : ' . $val . "<br />\n";
        $val = $zipvar;
}
  if ($field == "CountryName") {
     echo $field . ' : ' . $val . "<br />\n";
        $val = $countryvar;
}
  }
}
echo "</p>\n";

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
