PHP - Help With Foreach Loop Results
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?
Similar TutorialsI have a search form that has a drop down Code: [Select] <select name="radius" id="radius"> <option value="5">5 mi.</option> <option value="10">10 mi.</option> <option value="15">15 mi.</option> <option value="20">20 mi.</option> <option value="50">50 mi.</option> <option value="100">100 mi.</option> </select> I'm trying to limit the results in a foreach loop within what was selected. Meaning, if someone selects 10, results within 10 miles will show The foreach is Code: [Select] foreach ($stores as $k=>$v) { $output = "<h3 style='margin:0;padding:0'><b>".$storeinfo[$k]['MktName']."</b><br>(approx ".$v." miles)</h3>"; $output .= "<p style='margin:0 0 10px 0;padding:0'>".$storeinfo[$k]['LocAddSt']."<br>"; $output .= $storeinfo[$k]['LocAddCity'].", ".$storeinfo[$k]['LocAddState']." ".$storeinfo[$k]['zipcode']."</p>"; print_r($output); } $v being the distance. So I need to show only the results of $v that are less than $r. How would I go about doing this? Right now, $v displays numbers like 5.04, 173.9 and so forth. Can anybody help me out? Thanks in advance. Hello, i have the code below and i need to have all results in a variable as a string, inside the loop they are displayed how i want but outside will echo the last result. Thank You. Code: [Select] foreach($_POST as $key=>$value){ if (is_numeric($value)) { $valoare = "$value,"; } } echo $valoare; 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? I am working to echo the results in a while or for loop... Both of my sample codes work, but the results are wrong! The while loop ONLY echos a result IF the first record in the postings table matches the id passed (does not display a result unless the first record has a match) The if loop displays ALL listings with the same name (counts them all) so there are no unique listings! <?php $posts_by_city_sql = "SELECT * FROM postings WHERE id='$_GET[id]'"; $posts_by_city_results = (mysqli_query($cxn, $posts_by_city_sql)) or die("Was not able to grab the Postings!"); /* While Loop */ while($posts_by_city_row = mysqli_fetch_array($posts_by_city_results)) { echo "<li><a href='posting_details.php?id=$posts_by_city_row[id]'>$posts_by_city_row[title]</a></li>"; } /* For Loop */ $posts_by_city_row = mysqli_fetch_array($posts_by_city_results); for ($i=0; $i<sizeof($posts_by_city_row); $i++) { echo "<li><a href='posting_details.php?id=$posts_by_city_row[id]'>$posts_by_city_row[title]</a></li>"; } ?> Results with for loop (there are 7 total unique book names, but it's just counting the first match on id 7 times like below): AJAX for Beginners AJAX for Beginners AJAX for Beginners AJAX for Beginners AJAX for Beginners AJAX for Beginners AJAX for Beginners AJAX for Beginners How can I limit my foreach to displaying three results?

I am currently developing a module for my site that will allow me to classify each solution to help a disability by type. Type : Visual disability Solution : Add screen readers For this, I have a database in which these types and solutions are found. In this database, the solutions of one type or another are not in a defined order. They can be put randomly, when a user adds one. I need to display, in a table, these Types first (as a title), then the solutions corresponding to this type. I manage to generate a display thanks to a foreach loop, but my solutions are all mixed up and therefore not clearly sorted.
Visual disability Audio-described cut-scenes Highlighted path to follow Sensitivity settings for all the controls Screen readers on menus Slow down the game speed But I would need it to look like this: Visual disability Audio-described cut-scenes Highlighted path to follow Screen readers on menus Slow down the game speed Physical disability Sensitivity settings for all the controls In my example above, only the solution "Sensitivity settings for all the controls" is part of the "Physical disability" type. The rest is part of the "Visual disability" type. Here is the code I currently use to retrieve my information from my database and display it. It's a Wordpress.

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: General General New Features Testing Testing Sandbox Bugs 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 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? 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 For some reason I'm getting an invalid argument supplied for foreach error and I'm not sure why.

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

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. I am not sure what I am doing wrong in these loops.
hello why does my div move when i use a foreach loop ? if i use the code below i get the following i added a border style to the div so i can see that some are in and some are out: result 1 = not in a div result 2 = in a div result 3 = in a div etc then on the end i get a div with no result in it Code: [Select] function name(){ echo' <div id="divName">'; $a = Class::find_all(); foreach ($a as $ab){ $name = $ab->name; $dest = $ab->destination; <ul> <li><a href="index.php?pageID='.$dest.'">'.$name.'</a></li> </ul>'; } echo'</div>'; } thanks rick |
