PHP - How To Combine A String To Get A Foreach & Run In A Loop
Hello dear community, good day!
first of all: Merry Christmas to all of you!! How to combine / concatenate a *divided* string in order to use this combined / concatenated string in a loop where i run the $dom = new DOMDocument(); @$dom->loadHTMLFile('<- path to the file-> =60119'); and the following.... numbers - Note: they replace the ending!!! 60299 64643 62958 63678 60419 60585 60749 60962 and so on. ( Question: How to combine the string (in fact the string is an URL) so that i am able to build the URLs automatically. And that i am able to run all that in a loop - eg with foreach [probably this is the right way to do that]. I hope that i was able to explain the question so that you understand it. If i have to be more descriptive - just let me know! Many many thanks for a hint! db1 Similar TutorialsHello. I'm trying to append the loop keys and values into a string and store it into a hidden field. This is the code I have : Code: [Select] if (isset($_POST['ordered'])) { // We can assign $_POST['product'] to a variable to make it easier to type out $prod = $_POST['product']; // Throw a little intro to see how many they checked echo 'You selected ' , count($_POST['ordered']) , ' products.'; // Now we loop through it and get the IDS that were selected // Foreach lets you select the $key and the $value for each iteration of the loop // $strOrder = ""; foreach ($_POST['ordered'] as $key=>$id) { echo '<p/> ProdName: ' , $prod[$id]['name'] , '<br/> ProdPrice: ' , $prod[$id]['price'] , '<br/> ProdQty: ' , $prod[$id]['qty'] , ' <hr/>'; $strOrder .= $key . " " . $id; $TOT += $prod[$id]['price'] * $prod[$id]['qty']; } $TOT2 = $TOT + 55; echo '<input type="hidden" Name="TOT" value ="'. $TOT .'">'; echo '<input type="hidden" name="TOT2" value =". $TOT2 .'">'; echo '<input type="hidden" name="Order" value=". $strOrder . '">'; } strOrder does not get set to a value. Hi I have an array of items that I am currently displaying a foreach loop What I'm looking to do, is add a string, to all of items, a part from the last 4: foreach ($pager->getResults() as $items => $item) { echo $item->getName(); //need to add a string to this for the all but the last 4 } Thanks Hello, i have the code below and i need to have all results in a variable as a string, inside the loop they are displayed how i want but outside will echo the last result. Thank You. Code: [Select] foreach($_POST as $key=>$value){ if (is_numeric($value)) { $valoare = "$value,"; } } echo $valoare; $id[] = 12345; $id[] = 12345; $id[] = 12345; $id[] = 12345; $id[] = 12345; how would I combine these into a string "12345,12345,12345,12345,12345" Below is my output on the browser: Student: Kevin Smith (u0867587) Course: INFO101 - Bsc Information Communication Technology Course Mark 70 Grade Year: 3 Module: CHI2550 - Modern Database Applications Module Mark: 41 Mark Percentage: 68 Grade: B Session: AAB Session Mark: 72 Session Weight Contribution 20% Session: AAE Session Mark: 67 Session Weight Contribution 40% Module: CHI2513 - Systems Strategy Module Mark: 31 Mark Percentage: 62 Grade: B Session: AAD Session Mark: 61 Session Weight Contribution 50% Now where it says course mark above it says 70. This is incorrect as it should be 65 (The average between the module marks percentage should be 65 in the example above) but for some stange reason I can get the answer 65. I have a variable called $courseMark and that does the calculation. Now if the $courseMark is echo outside the where loop, then it will equal 65 but if it is put in while loop where I want the variable to be displayed, then it adds up to 70. Why does it do this. Below is the code: Code: [Select] $sessionMark = 0; $sessionWeight = 0; $courseMark = 0; $output = ""; $studentId = false; $courseId = false; $moduleId = false; while ($row = mysql_fetch_array($result)) { $sessionMark += round($row['Mark'] / 100 * $row['SessionWeight']); $sessionWeight += ($row['SessionWeight']); $courseMark = ($sessionMark / $sessionWeight * 100); if($studentId != $row['StudentUsername']) { //Student has changed $studentId = $row['StudentUsername']; $output .= "<p><strong>Student:</strong> {$row['StudentForename']} {$row['StudentSurname']} ({$row['StudentUsername']})\n"; } if($courseId != $row['CourseId']) { //Course has changed $courseId = $row['CourseId']; $output .= "<br><strong>Course:</strong> {$row['CourseId']} - {$row['CourseName']} <strong>Course Mark</strong>" round($courseMark) "<strong>Grade</strong> <br><strong>Year:</strong> {$row['Year']}</p>\n"; } if($moduleId != $row['ModuleId']) { //Module has changed if(isset($sessionsAry)) //Don't run function for first record { //Get output for last module and sessions $output .= outputModule($moduleId, $moduleName, $sessionsAry); } //Reset sessions data array and Set values for new module $sessionsAry = array(); $moduleId = $row['ModuleId']; $moduleName = $row['ModuleName']; } //Add session data to array for current module $sessionsAry[] = array('SessionId'=>$row['SessionId'], 'Mark'=>$row['Mark'], 'SessionWeight'=>$row['SessionWeight']); } //Get output for last module $output .= outputModule($moduleId, $moduleName, $sessionsAry); //Display the output echo $output; I think the problem is that it is outputting the answer of the calculation only for the first session mark. How in the while loop can I do it so it doesn't display it for the first mark only but for all the session marks so that it ends up showing the correct answer 65 and not 72? Hey guys, Got another question im hoping someone can help me with. I have a foreach loop (for use in a mysql query): foreach ($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)) { $query .= ", "; } } Cheers guys how do I echo "blah" after the first loop in a foreach loop and the in the rest of them echo "crazy"? I am working on a photo gallery script in which I need to show 9 images at a time. Here is my script so far Code: [Select] <?php foreach($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! For some reason I'm getting an invalid argument supplied for foreach error and I'm not sure why.

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.

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.

What am I missing? 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 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"> <tr> <?php //pega cada uma das operadoras do campo operadoras $operadoras = $opers_trazOperadoras ; $logos = explode(",",$operadoras); $x = 0 ; foreach ($logos as $v) { mysql_select_db($database_webroker, $webroker); $query_trazLogoOperadora = "SELECT * FROM tb_operadora WHERE tb_operadora.id_operadora = " . $v ; $trazLogoOperadora = mysql_query($query_trazLogoOperadora, $webroker) or die(mysql_error()); $row_trazLogoOperadora = mysql_fetch_assoc($trazLogoOperadora); $totalRows_trazLogoOperadora = mysql_num_rows($trazLogoOperadora); ?> <td><img src="http://www.we-broker...imagens_upload/<?php echo $row_trazLogoOperadora['logo']; ?>"> <?php do { ?> <?php } while ($x++ < 4); { echo $x ;?> </td></tr><tr> <?php } $x = 0 ; } ?> </table> The URL for this code is: http://valsegs.we-br...radorasPATO.php Tks! Hello all,
I have the following code (which obviously has unnecessary redundancy) and I would like to replace it with a ForEach loop in order to make the code shorter, and perhaps more efficient.
// validate input $valid = true; if (empty($store_name)) { $storeNameError = 'Please enter a Store Name'; $valid = false; } if (empty($item_description)) { $itemDdescriptionError = 'Please enter an Item Description'; $valid = false; } if (empty($qty_pkg)) { $qtyPkgError = 'Please enter Quantity or Package'; $valid = false; } if (empty($pkg_of)) { $pkgOfError = 'Please enter the Count/Quantity'; $valid = false; }At this point (being a newbie) I'm trying to wrap my head around the ForEach statement, but all I can achieve is to tie-my-knickers-in-a-knot. I know this is childs-play for some of you here, and I hope you can help me get a working ForEach statement. The following is the declaration of some related arrays (which potentially may be incorrect/inefficient as well): // Create an array of the fields we want to capture, along with their labels $fields = array( 'store_name'=>'Store Name', 'item_description'=>'Item Description', 'qty_pkg'=>'Qty / Pkg', 'pkg_of'=>'Pkg. Of', 'price'=>'Price', 'flyer_page'=>'Flyer Page #', 'limited_time_sale'=>'Limited Time Sale Days', 'nos_to_purchase'=>'Nos. to Purchase' ); // Create an array-type variable to keep track of validation errors $fieldsErrorMsgs = array( 'storeNameError'=>'Please enter a Store Name', 'itemDescriptionError'=>'Please enter an Item Description', 'qtyPkgError'=>'Please enter Qty or Pkg', 'pkgOfError'=>'Please enter the Qty', 'priceError'=>'Please enter the Price', 'flyerPageError'=>'Please enter the Flyer Page #', 'limitedTimeSaleError'=>'Please enter the Limited Time Sale Days', 'nosToPurchaseError'=>'Please enter the No(s). to Purchase' );And here's what I've tried...but there seems to be the following two problems with the ForEach portion of the code: 1) No errors are being displayed (inspite of the fact that I'm leaving all fields blank and clicking on the [Create] button 2) A row is being created (with all blank columns) $valid = true; $errors = array(); foreach($fields AS $field=>$label){ //The following line is using the ternary operator, it's basically a shorthand if/else assignment. $errors[$field] = (!isset($values['store_name']) || !strlen($values['store_name'])) ? $errors[$label] = 'Mandatory field, input required!' : NULL; if(!strlen($errors[$label])){ $valid = false; } } // insert data if ($valid) { $pdo = Database::connect(); $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $sql = "INSERT INTO shoplist (store_name,item_description,qty_pkg,pkg_of,price,flyer_page,limited_time_sale,nos_to_purchase,shopper1_buy_flag,shopper2_buy_flag,purchased_flag,purchase_later_flag) VALUES(?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)"; $q = $pdo->prepare($sql); $q->execute(array($store_name,$item_description,$qty_pkg,$pkg_of,$price,$flyer_page,$limited_time_sale,$nos_to_purchase,$initialize_flag,$initialize_flag,$initialize_flag,$initialize_flag)); Database::disconnect(); header("Location: index.php"); }The following is the FORM portion of the code, which is where the logic for displaying the "error messages" is defiend <form class="form-horizontal" action="create.php" method="post"> <?php foreach($fields AS $field=>$label){ //Print the form element for the field. echo "<label>{$label}:<br>"; //If the field had an error, display it. if(isset($errors[$field])){ echo ' <span class="error">'.$errors[$field].'</span><br>'; } //Echo the actual input.
