PHP - Need Help Ignoring Certain Items Acquired From A Foreach Loop
Basically I have the following code (posted below)
foreach($char_xml->characterInfo->characterTab->items->item as $item) { //get the item id $item_id = $item->attributes()->id; //get the xml doc for that item from wow armory $url = "http://www.wowarmory.com/item-info.xml?i=" . $item_id; $data = fetchXML($url); //create a SimpleXML object to parse the xml $item_xml = new SimpleXmlElement($data); //print the item's name echo "<li type=square>" . $item_xml->itemInfo->item->attributes()->name . " "; echo "<b>(" . $item_xml->itemInfo->item->attributes()->level . ")</b></br>"; //calculate gear score total $calc=$calc+$item_xml->itemInfo->item->attributes()->level; } echo '</ul>'; //print the total item level echo '<b>Total Additive Item Score (Equipped):</b>' . $calc; echo '<br>'; //calculate the average item level(equipped) $ilvl=$calc/16; echo '<b>Average Item Score (Equipped):</b>' . round($ilvl) . "<br><br>"; It is working relatively well for what I am trying to accomplish. It pulls xml data from wowarmory and uses it to calculate a player's "average item level". The problem I am running in to is if a player is equipped with certain items (that should not be calculated), the average is incorrect. I know atleast the shirt, tabard and off-hand need to be ignored IF equipped. I am trying to find something relative to all 3 items in the xml data and thus tell the script to disregard them. Here is a printed example of the array I am working with (warning its LONG). This is an example of a player that has these 3 extra items. Shirt (Block 4), off-hand(shield) (Block 17), and Tabard (Block19) : Quote SimpleXMLElement Object ( [@attributes] => Array ( [globalSearch] => 1 [lang] => en_us [requestQuery] => i=59458 [requestUrl]

"[Quality]=>1" which no other items should typically have. The big issue comes with the third odd ball (off hand). This off-hand could be a shield or any weapon with few exceptions depending on the player class. As I continue to try and figure this out, one solution could be to first take the previous two "[Quality]=>1" items out of the equation IF they exist, then ONLY IF there are 17 items remaining subtract the value of block/iteration 17 before calulating as usual. If 16 items, then just run $calc is it currently is. How would I accomplish this? I do not mind displaying the item's name, in fact I would prefer to keep the item list as it currently I just need to not include the said items in the item level average. I know this is probably relatively straight forward to accomplish and that I am a noob, but would be grateful of your assistance. Thanks. Similar TutorialsHi I have an array of items that I am currently displaying a foreach loop What I'm looking to do, is add a string, to all of items, a part from the last 4: foreach ($pager->getResults() as $items => $item) { echo $item->getName(); //need to add a string to this for the all but the last 4 } Thanks 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 Hi all, I have a table that shows data from an xml response that has been converted to an array. I have successfully managed to get that to work but it's showing more items than I want. I'm trying to isolate the items by state. There are 11 or so different states, of which I only want 7. I've tried the following with a while loop but I keep getting the message "undefined index: job_status" Here's my code (partial)
$projects = array();
$xml=simplexml_load_string($response) or die("Error: Cannot create object");
foreach($xml->Jobs->Job as $item) {
$projects[] = array(
'job_no' => (string)$item->ID,
'job_name' => (string)$item->Name,
'job_due' => (string)$item->DueDate,
'job_status' => (string)$item->State,
'job_staff' => (string)$item->Assigned->Staff->Name,
);
}
usort($projects, function($a,$b) {return $a['job_due'] <=> $b['job_due']; } );
$projects = array_reverse($projects);
while ($projects['job_status'] == ('Feasibility')
&& ('Measure Up')
&& ('Model Drawing')
&& ('Concept Design')
&& ('Developed Design')
&& ('Resource Consent')
&& ('Construction Documentation')) {
foreach ($projects as $proj) {
$formatted = date('d/m/Y', strtotime($proj['job_due']));
$job_no ="{$proj['job_no']}";
$job_name ="{$proj['job_name']}";
$job_due ="$formatted";
$job_status ="{$proj['job_status']}";
$job_staff ="{$proj['job_staff']}";

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 $array = array("1","2","3"); foreach ($array as $value){ echo $value; } Put its only echoing out 3, not the whole array. Hey Guys. I have a custom function that simply loops through an array and outputs the menu categories it finds in the array.
The foreach loop passes the function an array and the function returns the the value. The problem is that the function returns that last value.
Now I know some of you might say ... "Why don't you put the foreach inside the function and return the value when the foreach loop has been completed"
The reason why is because I to use that foreach loop through another function as well. I was thinking about using globals to get the return value. But just wanted to get your perspective on the best option here.
Please let me know what you guys think Thanks

Edited by eldan88, 06 July 2014 - 05:01 PM. 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[$field].'</span><br>';
}
//Echo the actual input. If the form is being displayed with errors, we'll have a value to fill in from the user's previous submission.
echo '<input type="text" name="'.$field.'"';
if(isset($values[$field])){
echo ' value="'.$values[$field].'"';
}
echo '/></label>';
}
?>
<div class="form-actions">
<button type="submit" class="btn btn-success">Create</button>
<a class="btn" href="index.php">Back</a>
</div>
</form>
Appreciate the help guys.
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. I have the following form the just has one field. Code: [Select] <html> <head> <title>Post</title> </head> <body> <form action="worldpay_callback.php" method="post"> <input type="text" name="username" id="username" /> <input type="submit" name="submit" id="submit" value="send" /> </form> </body> </html> I am then posting the form to the following page that is meant to loop through all of the post values and save them to a text file. For some reason my foreach loop doesn't seem to be working as done of the post values are getting written to the text file. Can anyone see anything I'm doing wrong? Code: [Select] $myFile ="notifications.txt"; $fh = fopen($myFile, 'w+') or die("can't open file"); foreach($_POST as $k=>$v) { $data = 'POST: Key:'.$k.' - Value:'.$v ." \n"; fwrite($fh, $data); } fclose($fh); return "[OK]"; Thanks for any help 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? 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? 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 |
