PHP - While Loop, Javascript And Ids
Hi I would really appreciate it if you could help me out.
Firstly the part of my script I'm having trouble with is just displaying titles of posts that have been put into a database, to display it i've got a while() loop which has the condition of $info = mysql_fetch_assoc($query) and although it's rather obvious I'll explain that the $query variable holds a mysql_query function. Displaying the data from the database is working as expected but at the end of the titles I have an "x" which leads to another page where the entries are 'deleted' but to improve the user interface I've added a button labelled "edit" outside the loop which has this event: Code: [Select] onclick=\"if (document.getElementById('del_but').style.visibility=='hidden') document.getElementById('del_but').style.visibility='visible'; else document.getElementById('del_but').style.visibility='hidden';\" src='_imgs/button_edit.png'>\" The elements that hold the id 'del_but' are the 'x' buttons aside the titles which are hidden with the use of the visibility styling but when the edit button is clicked only the first x button shows while the rest remain hidden. I'm not sure how I can solve this so if you have any suggestions for resolutions please respond, also the quotes are cancelled out on the code I provided as they're being echoed out. Thank you in advance Similar TutorialsHi. I have some javascript that I need to loop a set number of times. I have used a php query limited to 6. I then need to loop the javascript I have the same amount of times. However it is not looping. It loops through once and stops. Here is the code. //the query $Fetchactivityq = mysql_query("SELECT * FROM Activites WHERE clubid ='".$club['club']."' ORDER BY RAND() LIMIT 6 ") or die('activity error'); // then the images I want to loop further down the page <?php $i = 1; while($row = mysql_fetch_assoc($Fetchactivityq)) { ?> <li id="capslide_img_cont<?php echo $i;?>" class="ic_container"> <?php if ($row['Image']=='activityImage.jpg') { ?> <img src="/images/icons/activityImage.jpg" id="activityImage" /><?php } ?> </li> <?php $i++ } ?> // then at the bottom of the page the problem bit <script type="text/javascript"> $(function() { <?php $i = 1; do { ?> $("#capslide_img_cont<?php echo $i; ?>").capslide({ caption_color : 'white', caption_bgcolor : 'black', overlay_bgcolor : 'black', border : '', showcaption : false }); <?php $i++; } while($row1 = mysql_fetch_array($Fetchactivityq)); ?> }); </script> Thanks for your help Danny I have a problem where i am including javascript in a while loop but the id for the link always stays the same. start while loop..... $thread_topic_id = $topic_info->thread_topic_id; <script type="text/javascript"> link[0] = '<a href="index.php?forum=<?php echo $forum_id; ?>&topic=<?php echo $thread_topic_id; ?>">View Topic</a>' </script> the $thread_topic_id variable is always the last record to be displayed. I have 5 records pulled. how would i get it to display the correct id? Hi, I have a loop that I run to retrieve all wall posts. Each post, I want to start with textbox hidden. I have a javascript code for that, but it only does it with the last post in the loop. Is there a good solution for this? Code: Code: [Select] while($something = $something){ <table> <tr> <td> echo $wallpost; </td> </tr> <script type="text/javascript"> window.onload = hide_box(); function hide_box(){ document.getElementById('myText').style.visibility='hidden'; } </script> <form name="myForm" id="form1" method="post"> <input type="text" name="comments" id="myText" value="Enter in Text" onclick="this.value='';"/> </form> </table> } greetings! I have here codes that have two checkboxes, if 1 checkbox is checked, the other and textbox is disabled. I think my codes in js is functional, my problem is how to put it inside the mysql_fetch_array, I want to put those checkbox in every data fetch from my db. only the first data is affected ..i really appreciate your help guys! <?php include('connect-db.php');?> <html> <head> <script language = "Javascript" type="text/javascript" > function checkbox_disabled(tocheck,todisable,todisable2) { var x = document.getElementById(tocheck); if(x.checked){ document.getElementById(todisable).disabled=true; document.getElementById(todisable2).disabled=true; document.getElementById(todisable2).checked = false; }else{ document.getElementById(todisable).disabled=false; document.getElementById(todisable2).disabled=false; document.getElementById(todisable2).checked = true; } } </script> </head> <body> <?php echo "<table>"; $query = mysql_query("SELECT * FROM tbl_user") or die (mysql_error()); while ($row = mysql_fetch_array($query)) { echo '<tr>'; echo '<td>'.$row['user_Id'].'</td>'; echo '<td>'. $row['user_Fname'].'</td>'; echo '<td>'.$row['user_Lname'].'</td>'; echo "<td><input type='checkbox' id='checkbox1' value ='checked' onclick=checkbox_disabled('checkbox1','textbox1','checkbox2')></td>"; echo '<td><input type="checkbox" id = "checkbox2"><input type="text" id="textbox1" /><td>'; echo '</tr>'; } echo "</table>"; ?> </body> </html> Hey.
So the issue I'm having is consecutive loops on semi-large arrays, over and over. Consider this array:

Originally the data comes from ~2-3 database tables, of course. But to ilustrate the point, this is how the main array looks like. This array usually contains anywhere between 10-50 rows, each row containing at least 10 dates, with 10 key/values each.
And after setting up all the data, it needs to be processed. Currently this is how a friend of mine did it..
$placeDataHere = array();
foreach($firstArray as $key => $dates) {
foreach($dates as $date => $values) {
foreach($values as $key => $value) {
$placeDataHere['DV_' . $date]['SM_' . $key] = 'KS_' . $value;
//Followed by another ~50-70 lines of processing the 3 loop's data..
...
...
....
....
....
....
....
....
}
}
}
Obviously this isn't good practise, but we can't seem to figure out a better way of doing it, since both the data and the loops are horribly nested.
This loop and setup of $firstArray is run anywhere between 10-20 times/request, due to amount of users we wish to process. So, the result is that this code can take up to over 2-3 minutes to complete, which isn't really optimal performance.
In short my question is, are there any better methods of handling this with the data setup we currently have?
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 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 Good Evening - I am in the process of trying to call back a list of categories and sub categories using a WHILE LOOP inside of a WHILE LOOP.

In fact 2 questions about that. 1) In the FOR loop I have for example to do the loop 3 times. (needs to find 3 results withing the loop with if and else) When first time, he's gonna search within the WHILE loop that holds (for example) 10 records of the DB in a variable. He needs to search for rowid number 5, he found it He goes out of the WHILE loop and goes searching again but now for rowid number 2 Now it seem that the WHILE loop start searching for number 2 but won't start from his first row in the variable (10 rows from the db ). He start at row number 6 instead of beginning all over again !!! -> so the order of the numbers of rows MUST be in an ascending order, ortherwise he won't find them all ! But the numbers I have are NOT in an ascending order !!! Why doesn't the WHILE loop begin again from his row 1 in the variable ? FOR loop { WHILE loop { content here, break; } } 2) even when I get all the result in an ascending order, he won't go doing a second search but with a different rowid number that he gets from the FOR loop. It is giving me back indeed the right new rowid number, but the WHILE loop is doing nothing. I have put many echo "..."; and other stuff for checking but can't find the cause ! Here's the code : Code: [Select] // $ResultShow = 10 rows from mysql db if(isset($ResultShow)){ if (mysql_num_rows($ResultShow) >= 1){ //$linksuborder = "2,3,4"; $array1 = explode(",", $linksuborder); sort($array1); for ($n = 0; $n < count($array1); $n++){ // searchin for the right row id in the variable $ResultShow where we find the numbers for next loop $r1 = each($array1); While($Row2 = mysql_fetch_array($ResultShow)) { if($Row2["linkid"] == $r1['value']) // found it, now look for the numbers that we'll put in an array { echo "---here the content---"; // linksuborder is where numbers from row id's are stored like 5,2,8 //now put them in an array $array2 = explode(",", $Row2["linksuborder"]); sort($array2); for ($n2 = 0; $n2 < count($array2); $n2++){ $r2 = each($array2); ////// here searching for the sublinks ////// While ($Row3 = mysql_fetch_array($ResultShow)) { if($Row3["linkid"] == $r2['value']) // search for the right row id within the variable $ResultShow { echo "---here the content---"; break; // found it, so no need to do the rest of the loop } // end if } //end while ////// end searching for sublinks ////// } // end for } // end if else { echo "--- content here ---"; } } // end while } // end for } //end if } // end if Table : linkid linksuborder linktitle 1 2,3,4 2 9,7,8 mainlink1 3 10 mainlink2 4 mainlink3 5 6 7 sublink3 8 sublink2 9 sublink1 10 sublink4 -> linksuborder 2,3,4 are the row id's for the mainlink -> than we put the numbers 9,8,7 (also row id's) mentioned in row linkid 2 also in a new array -> now we can search for the sublinks -> get the details from row linkid 9, than 7, than 8 -> First mainlink is compleet, now go to row linkid 3 to do it all over again for the next mainlink... RESULTS from an sorted array -> sort($linksuborder); ------------------------------------------------------------- mainlink1 : sublink1, sublink2, sublink3 mainlink2 : **no result back but it should * mainlink 3 : **no result back but it should * Im trying to get percents from my DB Code: [Select] <?php $statisctis="SELECT COUNT(user_id) FROM `liked` WHERE ((DATE_SUB(CURDATE(),INTERVAL 1 DAY) <= date_liked) AND site_id='data->site_id') "; $datas = mysql_query($statisctis); $sum_datas = mysql_result($datas, 0); function Get_Percent($number,$total) { $percentage = round($number * 100 / $total); echo $percentage; } // Usage Get_Percent($sum_datas,$data->coins); ?> i got the result for one day i whant get result for last 12 days how can i do that? or i need to write 12 querys? Hey can someone use their intelligence and teach me how to change the below if statements to a loop? Code: [Select] if($h_rows) { $rl_rows = 8; } elseif($g_rows) { $rl_rows = 7; } elseif($f_rows) { $rl_rows = 6; } elseif($e_rows) { $rl_rows = 5; } elseif($d_rows) { $rl_rows = 4; } elseif($c_rows) { $rl_rows = 3; } elseif($b_rows) { $rl_rows = 2; } elseif($a_rows) { $rl_rows = 1; } Thanks The individual while loops work, but when I embed it within a while the parent loop runs, but the inner loop doesn't execute at all Code: [Select] while ($set3 = mysql_fetch_array($query2)){ while ($set2 = mysql_fetch_array($query)){ echo $set2['EmailAddress']; } } suppose i want to loop number like this (1.2.3.4.5.....100), but after every 5 number i want to echo another word and after that continue to the first loop: example: 1.2.3.4.5.W.6.7.8.9.10.W.11.12.13.14.15W.... can anyone help me about this. Thanks in advance Hello. I have a simple SQL query that returns a list of names, this is good and all is right with the world. I would like to associate a number with each person, a RANDOM number that will change each time I call the page. Desired result:
Number | Name
18 | Jeff
2 | Tammy
12 | Steve
10 | Phil
5 | Michelle
etc. etc.
Pool of numbers will be from 1 to 30. Sometimes the names pool will result in 18 rows or 27 rows or any number in between. I just need to assign a number from 1 to 30 to each name that is not the same each time. Here's my loop.
while ($row= mysql_fetch_array($result)) {
$lastname = $row["lastname"];
$firstname = $row["firstname"];
$numbers = range(1, 30);
shuffle($numbers);
foreach ($numbers as $number) {
}
echo "<tr>
<td class='results'>$number</td>
<td class='results'>$firstname $lastname</td>
</tr>";
}
Here's the problem I'm encountering:
1) If I leave the FOREACH inside the loop, I wind up with one or two repeated $number(s).
2) If I take the FOREACH outside the loop, I wind up with the first integer from the $numbers range repeated as many times as there are names
I'm just not sure how to achieve a unique designation for each name.
Could someone point me in the right direction? Thanks so much!
