PHP - Checkbox In A While Loop
How do I post the values that are in a while loop and add them to mysql table?
<form action="Test_Completed.php" method="post"> include '../Database/take_an_exam.php'; $intNumber = 1; while($info = mysql_fetch_array( $sql )) { echo "$intNumber, {$info['Que_Question']} <br />\n"; echo "<input type=\"checkbox\" name=\"choice1[]\" value=\"{$info['Que_Choice1']}\" /> "; echo "{$info['Que_Choice1']} <br />\n"; echo "<input type=\"checkbox\" name=\"choice2[]\" value=\"{$info['Que_Choice2']}\" /> "; echo "{$info['Que_Choice2']} <br />\n"; echo "<input type=\"checkbox\" name=\"choice3[]\" value=\"{$info['Que_Choice3']}\" /> "; echo "{$info['Que_Choice3']} <br />\n"; echo "<input type=\"checkbox\" name=\"choice4[]\" value=\"{$info['Que_Choice4']}\" /> "; echo "{$info['Que_Choice4']} <br />\n"; $intNumber++; } ?> <input type="submit" value="submit"/> </body> </html> </body> </html> Similar TutorialsHi , i am running a loop where i show 10 categories to edit , now i have values from previous loop of those categories and i wants checkbox to be selected of all those categories whcih i have in my loop but it only select one here is my code: <?php //$category_links is array which contains 3 values should be checked, there are total 10 categories $category_links = array(2,5,7); $query = $db->query("SELECT * from categories ORDER BY id"); while($row = $db->fetchArray($query)): ?> <input type="checkbox" name="categories[]" value="<?php echo $row['id']; ?>" > <?php echo $row['name']; endwhile; } i tried with for loop but it only select one category not other <?php //$category_links is array which contains 3 values should be checked $category_links = array(2,5,7); $query = $db->query("SELECT * from categories ORDER BY id"); for($i = 0;$i <= count($category_links);$i++) { while($row = $db->fetchArray($query)): ?> <input type="checkbox" name="categories[]" value="<?php echo $row['id']; ?>" <?php if($row['id'] == $category_links[$i]) { echo "checked=checked"; }?> ><?php echo $row['name']; ?> <?php endwhile; } Thanks for help Hi All, I've a loop which lists a series of options as checkboxes.

Hi everyone, I need to retain the checkbox selections after the form is submitted, but I'm stuck and wondering if anyone can offer some assistance? Thank you.

Hi all, I have a situation where I need to remember what check boxes where checked over pagination, I have managed to do this via the use of this: http://jamesfunk.com/wordpress/?p=65 The problem is that as the code stood: Code: [Select] <input type="checkbox" name="compare" value="<?php echo $list['jobseeker_id'];?>" class="remember_cb"/> It was treating one ticked checkbox as them all because they all have the same name and are in the a while loop! I countered this by changing the code to: Code: [Select] <input type="checkbox" name="compare<?php echo $list['jobseeker_id']?>" value="<?php echo $list['jobseeker_id'];?>" class="remember_cb"/> Which effectively now makes the checkbox name unique... i.e. compare{id}. The problem with this is that I can now no longer process it. This is my processing code: $jobseekers = $_POST['compare']; $i = 0; for($i; $i<count($jobseekers); $i++){ $query = "SELECT * FROM jobseekers WHERE jobseeker_id = '$jobseekers[$i]'"; $result = mysql_query($query) or die (mysql_error()); while ($row = mysql_fetch_array($result)) { // Spit out the required data } } As you can see I am trying to get the data from $_POST['compare'], which will obviously now be blank as I have had to make the name unique.... the trouble is I'm not sure how to actually process this. Can anyone help me out here? any help or advice would be greatly appreciated! many thanks, Greens85 Hey.
So the issue I'm having is consecutive loops on semi-large arrays, over and over. Consider this array:
$firstArray = array(
'row1' => 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.

Can someone explain me clearly how to use while loop inside while loop to print "*" in square shape. Thank you for your help. So I have a PHP parent page that is accesses that scans the database for the passed token in the URL and then replaces content on the template page using a loop. My issue is that I am trying to use a loop on the secondary page which causes the white screen of death. From what I can tell the loop inside a loop is causing the issue. I'll paste the code below, let a newbie know if you have any ideas or can point me in the right direction. Thanks everyone!

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 * Hi, This is part of my table code echo "<td align=\"center\"><font color=\"{$colors[$row['presenter1status']]}\">{$row['presenter1']}</font> <input type='checkbox' /></td>"; Now what I was hoping to do is write some code to check what is selected and what isnt to be then able to write some queries to the database. Can anyone give any pointers Thanks hallo everybody,
i have column in my guestbook table mysql database names vis.
i want make it possible for user to make theier comments invisible.
if user checked yes, the comment will be viewd. if he did not checked, the comment will not be viewed.
in my visibility.php the user can later change the value from yes to no or from no to yes.
i do not know how to make this possible in update.php file.
thank you very much for your help.

function get_checked($variable, $status){
if($variable == $status){
return 'checked="checked"';
}else{
return '';
}
}
<input type=\"checkbox\" name=\"emailNewsletter\" value=\"Yes\" ".get_checked($emailNewsletter, 'Yes')."> <input type=\"checkbox\" name=\"emailInbox\" value=\"Yes\" ".get_checked($emailInbox, 'Yes')."> $emailNewsletter = isset($_POST['emailNewsletter']) ? filter_input(INPUT_POST, 'emailNewsletter') : 'No'; $emailInbox = isset($_POST['emailInbox']) ? filter_input(INPUT_POST, 'emailInbox') : 'No';If no submit button clicked display mysql information $userInfo['emailInbox'] instead of 'NO' . How to do that? okay so i have like 7 checkboxes and it all works fine but when i check "other" it gives me a value of "ON" when i check all 6 previous boxes it gives me the correct value. i am not sure why this happens |
