PHP - Loop Within A Form To Sql
OK, I am displaying text fields from entries in a database, and want to update all the fields within the loop if the user hits Update.
Code: [Select] <table class="tablesorter"> <form action="<?php echo $_SERVER['PHP_SELF'];?>" method="POST"> <input type="hidden" value="<?php echo $agencyid; ?>" name="agencyid" /> <tr><h2>Appointments</h2></tr> <?php $select = mysql_query("SELECT * FROM appointment WHERE agencyid = '$agencyid'")or die(mysql_error()); while($appinfo = mysql_fetch_array($select)){ ?> <input type="hidden" value="<?php echo $appinfo['ID']; ?>" name="<?php echo $appinfo['ID']; ?>" /> <tr> <th>Carrier: </th><td><?php echo $appinfo['carrier'];?></td><th>Agency Code: </th><th><input type="text" value="<?php echo $appinfo['agentcode'];?>" size="15" maxlength="20" name="agencycode<?php echo $appinfo['ID']; ?>" tabindex="1" /></th> </tr> <?php } ?> <tr><th><input type="submit" value="Update" name="updateapp" tabindex="2" /></th></tr> </form> </table> I cant figure out an easy way to build a query off of the data once its submitted. Maybe a foreach loop on the POST then update as necessary? I cant wrap my mind around it. Similar TutorialsHi. I'm a PHP newbie. I'm trying to generate a form in a loop. The user would press the submit button and the loop would iterate. Ultimately, it's for a project that will read a large flat file and get 500 lines at a time that the user could page through. But, my little test case is far simpler. just increment a counter every time the user presses submit. What I've tried doesn't work; causes an endless loop rather than stopping each time for the user to hit submit. I've just cobbled this together from things I've seen here and elsewhere, so please be gentle. Any help would be greatly appreciated.

Ive tailored my test site to help describe the problems that I have. www.peterod.co.uk the form is the first link in the left hand bar. Here is the code that creates the form. <?php // make connection require_once "../classes/sqlconselfbuild.php"; $query = mysql_query("SELECT * FROM `materials` ORDER BY `id` ASC"); ?> <form action="../engines/testengine1.php" method="post"> <?php // results while ($row = mysql_fetch_array($query)): $id = $row['id']; ?> <p> id number: <input type="text" name="materials[<?php echo $id; ?>][name]" value="<?php echo $row['id']; ?>" /> Material: <input type="text" name="materials[<?php echo $id; ?>][material]" value="<?php echo $row['material']; ?>" /> Stage: <input type="text" name="materials[<?php echo $id; ?>] [stage]" value="<?php echo $row['stage']; ?>" /> Qantity: <input type="text" name="materials[<?php echo $id; ?>][quantity]" value="<?php echo $row['quantity']; ?>" /> Unit: <input type="text" name="materials[<?php echo $id; ?>][unit]" value="<?php echo $row['unit']; ?>" /> <br /> </p> <?php endwhile; ?> <input type="submit" name="submit" value="Submit" /> </form> I am unsure how to get this information to insert into the database. How do you use the UPDATE query with a loop generated form ? [php] here's what i am trying to accomplish, I would get array of name from my db and run a loop to create my form for ie. while($row=mysql_fetch_array($result)) { echo '<input type=text name=' . playername[$row['name']] . ' value=' . $row['playernumber']></input>'; } is this possible? when i use playername[] it works but i get 0,1,2 for index but i would like to use keys as my index. Hi all, I have the following code that generates a table of results from a MySQL query: $i=1; while($arr = mysql_fetch_array($result, MYSQL_NUM)) { $table .= "<tr>" ."<td width='5px';><input type='checkbox' name='transcheck".$i."'></td>" ."<td id='parent".$i."A'>".$arr[0]." ".$arr[1]."</td>" ."<td id='parent".$i."B'>".$arr[2]."</td></tr>" ."<tr style='display:none'><input type='hidden'; name='transemail".$i."'; value='".$arr[9]."'></tr>"; $i++; } $table .= "</table>"; echo $table; As you can see it generates a table containing (amongst other things): checkboxes: transcheck1,2........9...etc. hidden inputs: transemail1,2........9...etc. This table is inside a form, so that the above gets posted to another php file. What I now want to do in this 2nd php file, is to retrieve all the checkboxes and hidden inputs and then to display the values of the hidden inputs, where the corresponding checkbox has been checked. So e.g. if transcheck1, transcheck3 and transcheck12 have been checked, then I want to display transemail1, transemail3 and transemail12. I can see that this should be relatively straightforward, but I'm fairly new to this stuff, could someone pls help me out? Thanks! I have been trying to figure this out for a friend of mine that wants this done, but I have begun to think that it just isn't possible - for security reasons... I need to run a HTML form on an external website for each url selected - so run through a loop processing the form over and over... Something like: for($i=0;$i<=count($urls);$i++){ // run form on http://website.com using $url[$i] } Can this be done? I am thinking that without recreating the PHP script the site uses in the form, it can't. So i have an event page where it will show the next 3 events, then i need logged in users to click either of two buttons to say there attending or not attending. i have the below code showing events, and the <form> and the submit and both buttons, but if i submit 1 button on event ID: 1 it inserts data into the database but for event ID: 2, and if i click the button on event ID :2 it also puts it into database with eventid:2 so no matter which event i click it seems to submit data with the latest event ID shown on page, and not for "each" event seperatly. i have moved the submit query everywhere around and still same results or duplicate results if its in the loop. i assume its looping the submit and only submitting the latests event ID.
<?php
if ($result = $con->query("SELECT * FROM events ORDER BY id ASC LIMIT 3")) {
if ($result->num_rows > 0) {
while ($row = $result->fetch_object()) {
$event_id = $row->id;
// set up table and echo data!
echo "<table border='1' cellpadding='2' width='50%'>";
echo "<tr><td>";
echo "<p><img src='images/raid_banners/" . $row->bannerimg . "'>" . $row->name . " (iLvl: " . $row->itemlevel . ")</p>";
echo "<p>Event Starts: " . $row->datestart . " - " . $row->timestart . "</p>";
echo "<p>Event Ends: " . $row->dateend . " - " . $row->timeend . "</p>";
echo "<p>Raid Lead: " . $row->raidlead . "</p>";
echo "<form action='' name='$event_id' method='post'>";
// Process and populate SELECT form element
echo "<select name=\"charname\">";
$sql = mysqli_query($con, "SELECT * FROM characters WHERE userid = $userid");
while ($row = $sql->fetch_assoc()){ echo "<option value=\"{$row['id']}\">{$row['charname']}</option>"; }
echo "</select>";
echo "<input type='hidden' name='raidid' value ='$event_id'>";
echo "<input type='hidden' name='action' value='submit' />";
echo "<input type=\"submit\" name=\"submit\" value=\"going\">";
echo "<input type=\"submit\" name=\"submit\" value=\"notgoing\">";
echo "</form></td></tr></table><br><br>";
}
if(isset($_POST['action'])){
$charid = $_POST['charname'];
$submit = $_POST['submit'];
// Submit the data from dropdown in the form
mysqli_query($con,"INSERT INTO eventsignup (eventid, charid, userid, status) VALUES ('$event_id', '$charid', '$userid', '$submit')"); }
}
else { echo "No results to display!"; } }
else { echo "Error: " . $con->error; }
$con->close();

any help would be awesome. im tearing my hair out here. Hey Guys. I crearted a class that goes loops through the session cart and displays the items. The problem that I am facing is when a return the values from a method it only brings back the first item that was added to the cart. It doesn't out out all the values.
However when I echo the the values straight from inside the method it shows all the items it looped through. I have tried every possibly thing to have all the items be displayed but I couldn't find to seem a solution.
Please note that I skipped a lot of the code in the example below for breviety. Such as instantiation, and other things. There maybe some syntax errors as well. I just did a breif copy and paste
Any help would be really appreciated!!!

However, this time I cannot find the answer I need/recognise/understand.. I have a form and want to conduct tests on each field returning an error message as a session variable if the test fails. The test will be different for some of the fields, and the error message is specific to each field. If there is an error in any one of the fields I want to be redirected to a failure page where all of the error messages are displayed, otherwise I am sent on to another page. I have already written and tested a function to sanitise the incoming form data, so that's not a problem - it's just how to loop through and test. I can guess that there are many ways to do this but I need to understand why one option is better than another, and follow the syntax used (it's all part of my steep learning curve) The approach I have thought to use is to create an array holding the field name, the test and the message, then loop through using foreach, applying the array values into the test and creating the error message....but it's not working for me. The other method is to declare a variable $Stop='No' and if the loop identifies an error, part of the output is to change this to 'yes' and through that redirect to the error page. I'd really welcome your advice and tuition....cheers.. my code so far is... Code: [Select] $Stop='No'; $StaffPassCheck=sanitisealphanum($_POST['PasswordCheck']); $Errors[0]['value']= sanitisealphanum($_POST['FirstName']); $Errors[0]['message']='Please re-enter your name'; $Errors[0]['test']=($StaffFname=""); $Errors[1]['value']= sanitisealphanum($_POST['Surname']); $Errors[1]['message']='Please re-enter your surname'; $Errors[1]['test']=($StaffSname=""); $Errors[2]['value']= sanitisealphanum($_POST['Post']); $Errors[2]['message']='You must select an option'; $Errors[2]['test']=($StaffPost="Select Value"); $Errors[3]['value']= sanitisealphanum($_POST['Username']); $Errors[3]['message']='You must select an option'; $Errors[3]['test']=($StaffUser=""); $Errors[4]['value']= sanitisealphanum($_POST['Password']); $Errors[4]['message']='Please re-enter your password'; $Errors[4]['test']=($StaffPass=""); $Errors[5]['value']= sanitisealphanum($_POST['PasswordCheck']); $Errors[5]['message']='Sorry, your passwords do not match'; $Errors[5]['test']=($StaffPass===$StaffPassCheck); foreach ($Errors as $key => $Value){ if ( $Errors['test']=true ){ $Stop='Yes'; return $_SESSION[$key]=$Value['message']; } } if ($Stop='Yes'){ header('Location.test.php'); die(); }else{ header('Location.indexp.php'); } 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. It works on a different part of the site within the admin panel but not here.

I need divs wrapped around every set of 5 images so if there is a total of 8 images then there would be 2 sets of divs (first with 5 images, second with 3 images) and if there was 12 images then there would be 3 sets of divs (first two with five images, last one with 2 images) etc etc What am I doing wrong and is there an easier way to do this? http://pastebin.com/QfsFxe4G Thanks! 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! Here is the chunk of code from the parent page with the loop function.... // output pre content eval("\$preContent = \"$preContent\";"); print_r( replaceChar($preContent) ); $sqlSearch = "SELECT * FROM ".$row[tdbd_name]."

LIMIT ".MAX_ROWS; $resultSearch = mysql_query($sqlSearch); while($displayrows = mysql_fetch_assoc($resultSearch)) { $display = replaceTokens($loopTemplate); $display = str_replace('\\', '[backslash]', $display); $display = str_replace('[%', '$displayrows[', $display); $display = addslashes(str_replace('%]', ']', $display)); $display = replaceTokens($display); $display = changeCase($display); eval("\$display = \"$display\";"); $display = stripslashes($display); $display = str_replace('[backslash]', '\\', $display); $display = replaceChar($display); print_r( $display ); } // output post content And here is the loop function from the page that the above code loops through replacing tokens in. <?php $mySQLServer = "xxxxxxxxx"; $mySQLUser = "xxxxxxxxxx"; $mySQLPass = "xxxxxxxx"; $mySQLDB = "xxxxxxxxxxxxx"; $SQLToday = date("m/d/y") .

Thank you I hope somebody can help me.. A WHILE loop in a FOR loop problem Script about links and sublinks from 1 table. 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, I am new to PHP. Can someone explain me clearly how to use while loop inside while loop to print "*" in square shape. Thank you for your help. |
