PHP - If Row Doesnt Exist
hello, i am having an issue with tables using incorrect data.
i have 2 columns, first is employee name, second is location if the employee doesnt have a location for the current day, it is telling me he is at the same location as the guy in the row above him. i need this to be blank. is this possible? Similar Tutorialshi, i have a select which gets todays schedule for each user. sometimes that user doesnt have anything for todays date and it will display the info from the user above him. how can i make it so it stays blank if there is no record? I have an array like so Array (14) ( | ['0'] => Array (5) | ( | | ['name'] = String(7) "Pikemen" | | ['hp'] = Integer(1) 0 | | ['atk'] = Integer(1) 5 | | ['def'] = Integer(1) 5 | | ['rng'] = Integer(2) 15 | ) | ['1'] => Array (5) | ( | | ['name'] = String(7) "Pikemen" | | ['hp'] = Integer(1) 0 | | ['atk'] = Integer(1) 5 | | ['def'] = Integer(1) 5 | | ['rng'] = Integer(2) 15 | ) | ['2'] => Array (5) | ( | | ['name'] = String(7) "Pikemen" | | ['hp'] = Integer(1) 0 | | ['atk'] = Integer(1) 5 | | ['def'] = Integer(1) 5 | | ['rng'] = Integer(2) 15 | ) | ['3'] => Array (5) | ( | | ['name'] = String(7) "Pikemen" | | ['hp'] = Integer(1) 0 | | ['atk'] = Integer(1) 5 | | ['def'] = Integer(1) 5 | | ['rng'] = Integer(2) 15 | ) | ['4'] => Array (5) | ( | | ['name'] = String(7) "Pikemen" | | ['hp'] = Integer(1) 0 | | ['atk'] = Integer(1) 5 | | ['def'] = Integer(1) 5 | | ['rng'] = Integer(2) 15 | ) | ['5'] => Array (5) | ( | | ['name'] = String(7) "Pikemen" | | ['hp'] = Integer(1) 0 | | ['atk'] = Integer(1) 5 | | ['def'] = Integer(1) 5 | | ['rng'] = Integer(2) 15 | ) | ['6'] => Array (5) | ( | | ['name'] = String(7) "Pikemen" | | ['hp'] = Integer(1) 0 | | ['atk'] = Integer(1) 5 | | ['def'] = Integer(1) 5 | | ['rng'] = Integer(2) 15 | ) | ['7'] => Array (5) | ( | | ['name'] = String(7) "Pikemen" | | ['hp'] = Integer(1) 0 | | ['atk'] = Integer(1) 5 | | ['def'] = Integer(1) 5 | | ['rng'] = Integer(2) 15 | ) | ['8'] => Array (5) | ( | | ['name'] = String(7) "Pikemen" | | ['hp'] = Integer(1) 0 | | ['atk'] = Integer(1) 5 | | ['def'] = Integer(1) 5 | | ['rng'] = Integer(2) 15 | ) | ['9'] => Array (5) | ( | | ['name'] = String(7) "Pikemen" | | ['hp'] = Integer(1) 0 | | ['atk'] = Integer(1) 5 | | ['def'] = Integer(1) 5 | | ['rng'] = Integer(2) 15 | ) | ['10'] => Array (5) | ( | | ['name'] = String(7) "Pikemen" | | ['hp'] = Integer(1) 0 | | ['atk'] = Integer(1) 5 | | ['def'] = Integer(1) 5 | | ['rng'] = Integer(2) 15 | ) | ['11'] => Array (5) | ( | | ['name'] = String(7) "Pikemen" | | ['hp'] = Integer(1) 0 | | ['atk'] = Integer(1) 5 | | ['def'] = Integer(1) 5 | | ['rng'] = Integer(2) 15 | ) | ['12'] => Array (5) | ( | | ['name'] = String(7) "Pikemen" | | ['hp'] = Integer(1) 0 | | ['atk'] = Integer(1) 5 | | ['def'] = Integer(1) 5 | | ['rng'] = Integer(2) 15 | ) | ['13'] => Array (5) | ( | | ['name'] = String(7) "Pikemen" | | ['hp'] = Integer(1) 0 | | ['atk'] = Integer(1) 5 | | ['def'] = Integer(1) 5 | | ['rng'] = Integer(2) 15 | ) ) what i want to do is add the details to a new multi dimensional array but only add one each like so array( ['units'] = array( ['name'] => 'Pikemen', ['lost'] => 14 ) ) basically where the HP is 0 in the first array i need to add them to the second if the name is unique. I have tried array unique but it didnt seem to work. Any ideas?

Code: [Select] if(isset($_POST['search'])) { $tool=$_POST['tool']; echo "<table border='1' style='border-collapse: collapse' bordercolorlight='#000000' bordercolordark='#000000' width='98%' align='center'>"; echo "<tr><td width='100%' colspan='5' align='center'><b>Tool List - $tool</b></td></tr>"; echo "<tr> <th align='center'>Tool</th> <th>Location</th> <th>Status</th> </tr>"; $result = mysql_query("SELECT * FROM tools WHERE toolgroup LIKE '%$tool%' ORDER BY tool"); while($row = mysql_fetch_array($result)) { $id=$row['id']; $tool=$row['tool']; $barcode=$row['barcode']; $location=$row['location']; $result2 = mysql_query("SELECT * FROM toolout WHERE toolid = '$id' ORDER BY id ASC"); while($row2 = mysql_fetch_array($result2)) { $status=$row2['status']; $who=$row2['who']; $datechanged=$row2['datechanged']; $datechanged1 = date( 'M j, Y', strtotime($datechanged) ); if("$status" == "1") { $statusout="<font color='#0000FF' size='4'>IN</font><br /><a href='toolout.php?tool=" . $id .

Hey, I have this code below which seems to completely fail sending my laptop cpu fan on a frenzy. All I am wanting to do is find whether the id in the url is located inside the array below else state its not in an error saying its not a valid id (for people who change the url shown below). At the moment it doesnt like the else statement if the isset clause it not true. (I have also tried, array_key_exists) All I can think is that it get stuck looking for an id that doesnt exist inside the array but keeps searching though I dont know much about arrays etc. Besides this when a id is inside the array the script works like I want it to. Any ideas would be much appreciated as this is hold me back at the moment Code: [Select] //url: http://localhost/website/shop.php?id=10197 // Array is built from table prior to this as it will grow in size $_SESSION['storesProducts'] = Array ( [10197] => 0 [10198] => 0 [10199] => 1 [10200] => 1 [10201] => 1 [10202] => 1 [10205] => 0 [10206] => 1 [10207] => 1 ) if(isset($_SESSION['storesProducts'][$id])){ $storesProducts = $_SESSION['storesProducts'][$id]; if($storesProducts == 0){ $list = $this->displayCategories($id); }else{ $createProducts = new constructProducts(); $products = $createProducts->pagination($id); } }else{ $list = "ITS NOT HERE"; } $output = new outputShop(); $output->display($list, $products); i have error where my code should update existing data where id exist, it get updated ..but the others data is disappeared .only the data updated is remained $sql1 ="select*from semakan_dokumen where email='$stdEmail'"; $sqlsearch1 = mysqli_query($dbconfig,$sql1); $resultcount1 = mysqli_num_rows($sqlsearch1); if($resultcount1 > 0){ $query1=("UPDATE semakan_dokumen set student_id='$noMatrik', email= '$stdEmail', surat_tawaran='$fileName', ic='$fileName1',sijil_lahir='$fileName2',sijil_spm= '$fileName3',sijil_sekolah= '$fileName4', sijil_dip= '$fileName5',sej_julai='$fileName6',bm_julai='$fileName7',muet='$fileName8', mid1='$fileName9',yuran= '$fileName10',umpa_bend1= '$fileName11',umpa_bend2='$fileName12',bpkp='$fileName13', penaja='$fileName14',kesihatan= '$fileName15', jhepa='$fileName16' where email= '$stdEmail' "); }else{ //filezip $query1 = "INSERT INTO semakan_dokumen (email,surat_tawaran,ic,sijil_lahir,sijil_spm,sijil_sekolah,sijil_dip,sej_julai,bm_julai,muet,mid1,yuran,umpa_bend1,umpa_bend2,bpkp,penaja,kesihatan,jhepa) VALUES ('$stdEmail','$fileName','$fileName1','$fileName2','$fileName3','$fileName4','$fileName5','$fileName6','$fileName7','$fileName8','$fileName9','$fileName10','$fileName11','$fileName12','$fileName13','$fileName14','$fileName15','$fileName16')"; }
if so how would they be used in a mysql query? hi, im having trouble adding a get variable to a url if one already exists. eg current url = http://www.example.com/index.php?var1=something i want to be able to change this to new url = http://www.example.com/index.php?var1=something&var2=another even so i can have a few get variable there. I can add the first var through a form or link, but how would i add more through a link or through the header function? I am positivly stuck. Thanks Hi.. So what i want to do is basicly to check if id XX exist in my database. How can this be done? Im thinking of something like: if(xx exist){do this} else{do this} Iv'e tried google etc before i posted here, but couldent really find anything where i found a soutable answer.. Hope someone can help! (: Hi all, I want to make a script that identifies if an image JPG file exists. Would somthing like this work? <?php $file = "images/image.jpg"; if ($file > 0) { echo "file exists"; } else { echo "no file"; } ?> Does the concept of a "Namespace" exist in PHP? If so, how do you use them? This is a snippet from ASP.NET that made me ask this question... Quote <%@ Import Namespace="System.Data" %> <%@ Import Namespace="System.Data.SqlClient" %> TomTees Gud pm!! So i made this script to check if a username and password exist but it kinda fails me. It gives me a database connection error from my confirm_query() which means it returned false? so here's my code: Code: [Select] function check_if_exist($username, $password) { global $connection; $query = "SELECT username, hashed_password"; $query .= "FROM users "; $query .= "WHERE username = '$username' "; $query .= "AND hashed_password = '$password' "; $query .= " LIMIT 1"; $result_set = mysql_query($query, $connection); confirm_query($result_set); if(mysql_num_rows($result_set) == 1) { return true; } else { return false; } } my confirm_query(): Code: [Select] function confirm_query($result) { if(!$result) { die("Database connection failure ". mysql_error()); } } I have a another script to check if the email exist and it works perfectly, i dunno why this won't work properly.. maybe another simple mistake.. Any ideas or Violent reaction? Thanks! Hi all - I have a form that let's a user upload an image to their specified folder. The folder is determined by the "password" the user inputs. The "password" is really just the folder name on my server, so if "michael83" was entered as a password, the directory would be "images/uploaded/michael83". That works great now, thanks to a forum user, litebearer. Thanks again. Here's my second question: I'm working on a "history" page so that a user can input their "password" and view their upload history. The form works right now. If you enter a "password" (folder name) that exists, the code will spit out the contents / files. So, now I'm looking for two things: (1) if a user enters a "password" (folder name) that exists, but there are no files in the folder, "There are no files in the $dir directory." will be echoed; and (2) if a "password" (folder name) is entered that does NOT exist, "The directory $dir does not exist." will be echoed. Here's my code so far (minus the if statements I'm looking for): $dir = $_POST['password']; $path = "images/uploaded/". $dir; $dir_handle = @opendir($path); while ($file = readdir($dir_handle)) { if($file == "." || $file == ".." ) continue; if(isset($_POST['Submit'])) $url = "http://www.mysite.com/". $path . "/" . $file; { echo "<a href=\"$url\">$url</a><br />"; }} closedir($dir_handle); As always, many thanks in advance for any help on this. Basically this gets a number from a table on my DB, and displays the content relevent to that number...the second part checks for that number and gets other information according to that number... what i want to do is make sure that the number from the first query exists in the table from the query, and if it doesn't print out and error saying "there is no information" or whatever.. anyone have an idea? hopefully this makes sense Code: [Select] <?php require_once('Connections/myConnect.php'); $detnum = $_GET['Details']; $detinfo = mysql_query("SELECT* FROM `Agency Stores - Table 1` WHERE F11=".$detnum); $det = mysql_fetch_array($detinfo); $salesnum = $det['F3']; $salesinfo = mysql_query("SELECT* FROM `By Agency Store _` WHERE store_store=".$salesnum); $sales = mysql_fetch_array($salesinfo); if(mysql_query("SELECT* FROM `By Agency Store _` WHERE store_store=".$salesnum)){ } ?> Hello, i want to check whether image exist or not, but i can't get any data about it.
