PHP - Loop Input.
hi , i have build an search engine .
i don't know really how to output the results. i have done something like this . $qry = mysql_fetch_assoc(mysql_query("SELECT `search2`FROM `search` WHERE `search1`='%".$search."%' ")); echo $qry['search2']; but it output only 1 result , i wanna know to to output all the results he find. thanks , Mor. Similar TutorialsHello, I have a script that displays that uses a while loop in php to display all of the records. For each record, I added an input text box with a button to update one of the fields in the record set. When I run the script only the first listing will update and the subsequent listings on the page will not update. Should I go about this set up differently? Code: [Select] <html> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <head> <?php session_start(); ?> <script language="JavaScript"> TargetDate = "11/18/2011 6:00 PM"; BackColor = "palegreen"; ForeColor = "navy"; CountActive = true; CountStepper = -1; LeadingZero = true; DisplayFormat = "%%D%% Days, %%H%% Hours, %%M%% Minutes, %%S%% Seconds."; FinishMessage = "It is finally here!"; </script> <script language="JavaScript" src="http://scripts.hashemian.com/js/countdown.js"></script> <!-- function timedRefresh(timeoutPeriod) { setTimeout("location.reload(true);",timeoutPeriod); } // --> <script type="text/JavaScript"> function showCurrentPrice(str,str1) { if (str=="") { document.getElementById("priceElement").innerHTML=""; return; } if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById("priceElement").innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","getPrice.php?q="+str+"&s="+str1,true); xmlhttp.send(); } </script> <?php $con=mysql_connect("xxxx", "xxxx", "xxxx") or die ("cannot connect"); mysql_select_db("tab_test") or die ("cannot select database"); echo 'Welcome ' .$_SESSION['username'].

I have two tables for use in a quiz program--one table for questions and one table for answers. I'm thinking about looping through all the questions, one at a time, and all the answers that correspond to the given question, echoing the form: the radio buttons and the submit button, and have the program pause to wait for the submit button to be clicked before looping to the next question/answer set. I'm assuming I'll need to make two queries, one for the Questions table, and one for the Answers table, incrementing the QuestionID with each loop (or randomizing them and marking them as asked so the same question doesn't come up multiple times), processing the answers before the next loop, etc. 1. Is this possible? 2. Is this a good approach? 3. Where would I look to learn how to do all this? I don't have any code to show because I haven't yet written anything about this. I'm still thinking about how I would do it. I have to learn about randomizing, and about nested queries, and about a few other things. I'm just tossing this "out there" for some ideas. Thanks to all. Rich Hollenbeck 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 I hope I can explain what is happening. I have created two forms in PHP. The first 'almost' works, i.e. it shows the data. But I have two problems - 1) the second pulldown menu is always empty and 2) $value from the first pulldown menu ALWAYS equals the last entry thus the last 'if' in the function subdomains ($domains) is always called (but still empty). The code may explain this better than me:
<!DOCTYPE html>
<html>
<body>
<!-- processDomains.php is this file - it calls itself (for testing purposes so I can see what is happening) -->
<form action="processDomains.php" method="post">
<?php
// create the domains array (there are actually several entries in the array but I cut it down for testing)
$domains = array (1 => 'Decommission', 'Migration');
echo "Select Domain:";
echo "<br>";
// Make the domain pull-down menu - this displays correctly
echo '<select name="domain">';
foreach ($domains as $key => $value) {
echo "<option value=\"$key\">$value</option>\n";
}
echo '</select>';
// input doesn't matter what is 'submitted', always goes to last $value
echo '<input type="submit" name="submit" value="Submit">';
// call function subdomains
subdomains ($value);
function subdomains ($domains) {
// define values for each array - each array contains available choices for the subdomain pulldown menu
$migration = array (1 => 'Application Migration', 'Application Patch', 'Application Upgrade');
$decommission = array (1 => 'Applications', 'Servers', 'Storage');
if ($domains === 'Migration') {
echo "Select subdomain:";
echo "<br>";
// Make the Migration pull-down menu
echo '<select name="migration">';
foreach ($migration as $key => $value) {
echo "<option value=\"$key\">$value</option>\n";
}
echo '</select>';
} else if ($domains === 'Decommission') {
/* ===
* since 'Decommission' is the last entry in the 'Domains' pulldown list, $value ALWAYS equals
* 'Decommission' and $domains equals $value. So this menu SHOULD work but is always
* empty. Thus, two problems - the pulldown menu is always empty and $value isn't based
* upon user input.
*/
echo "Select subdomain:"; // this prints so I know I'm in 'Decommission (I eliminated the echo "$domain" to show I'm always coming here)'
echo "<br>";
// Make the 'Decommission' pull-down menu
echo '<select name="decommission">';
foreach ($decommission as $key => $value) {
echo "<option value=\"$key\">$value</option>\n";
}
echo '</select>';
echo '<input type="submit" name="submit" value="Submit">'
) // end of 'if-else'
} // end of function 'subdomain'

Let me say thank you in advance and I appreciate the help! I know I'm doing something (or more than one thing) wrong and I hope someone can tell me what it is.
Best Regards!
Edited by mac_gyver, 19 January 2015 - 09:37 PM. code tags around posted code please I am writing a script that will parse my PHP classes and check for things like coupling, visualize my objects and connections, dependencies, check for convention usage, etc.
So, I have a simple file upload. I'm never saving the files, just get contents and dump the file and work with the string version.
I'm writing it for me, but I figure I might want to open it for others to use in the future, so I may as well write it that way to begin with -- so I need to validate user input. Problem is, the user input is supposed to be valid PHP code. I'm thinking that, as long as I'm careful, I shouldn't be executing any code contained in strings, but I'm no security expert and I want a warm fuzzy that my thought on this is correct. What kinds of things do I need to look out for? Is it possible to inject when working with strings?
My initial thought is to regex the entire file and replace key portions with known replacements. So ( and ) would become !* and !^ or $ would become @~ (combinations that -- I think -- don't make sense to php?) But that may be completely unnecessary processing time if I'm not in any danger, here. Thanks ahead of time for any help.
PS - as a side question -- what's the best way to verify a file is a php file? I know of getimagesize for images, but should I just check for <? to verify it's php? That seems like it would be too easy to fool -- then again, it might not matter much.

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. Here it only calls one sub category and moves on to the next parent category instead of finishing the loop and pulling all sub categories out... // CATEGORIES $query = "SELECT * FROM cat"; $result = mysql_query($query); while($row = mysql_fetch_array($result, MYSQL_ASSOC)) { $catid = $row['id']; $catname = $row['name']; $output .= "<li class=\"level0 nav-2 parent\" onmouseover=\"toggleMenu(this,1)\" onmouseout=\"toggleMenu(this,0)\"> <a href=\"product.php?cat=$catid\"> <span>$catname</span> </a>\n"; $querynav = "SELECT * FROM subcat WHERE pid = '$catid'"; $resultnav = mysql_query($querynav); while($array = mysql_fetch_array($resultnav, MYSQL_ASSOC)) { $subcatid = $row['id']; $subcatname = $row['name']; $output .= "<ul class=\"level0\"> <li class=\"level1 nav-2-1 first\"> <a href=\"product.php?cat=$catid&subid=$subcatid\"> <span>$subcatname</span> </a> </li> </ul> </li>"; } } I have a calendar select date function for my form that returns the date in the calendar format for USA: 02/16/2012. I need to have this appear as is for the form and in the db for the 'record_date' column, but I need to format this date in mysql DATE format (2012-02-16) and submit it at the same time with another column name 'new_date' in the database in a hidden input field. Is there a way to do this possibly with a temporary table or something? Any ideas would be welcome. Doug 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]." WHERE ".$sqlKeyword." 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") .

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! 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 have while loop inside while loop but I encountered problem in displaying data inside while loop or the second while loop. here is my code: Code: [Select] <?php error_reporting(0); $con = mysql_connect('localhost', 'root',''); if (!$con) { echo 'failed'; die(); } mysql_select_db("mes", $con); ?> <script type="text/javascript"> function showDetails(pcode) { var clickElement = pcode.value; var click_id = pcode.id; // var value_ = document.getElementById(click_id).checked // = document.getElementById(clickElement).checked; //var Table = (document.getElementsByName('list')[0].value); var Table = document.getElementById('kanban_list'); var rows = Table.rows; var strSelect = document.getElementById(click_id).value; //alert(strSelect) for (var i = 0; i < rows.length; i++) { var row = rows[i]; //row.style.display = (row.id.substr(0,3) == strSelect) ?

Thank you I hope somebody can help me.. Hi people, I really hope you guys can help me out today. I'm just a newbe at php and i'm having real trouble. Bassically all I want to do is have a user type in a company name in a html form. If what the user types in the form matches the company name in my php script i want the user to be sent to another page on my site. If what the user types in the form doesnt match the company name in my php script i want the user to be sent to a differnt page like an error page for example. this is my html form: Code: [Select] <form id="form1" name="form1" method="post" action="form_test.php"> <p>company name: <input type="text" name="company_name" id="company_name" /> </p> <p> <input type="submit" name="button" id="button" value="Submit" /> </p> </form> And this is the php code I'm trying to process the information on: Code: [Select] <?php $comp_name = abc; if(isset ($_POST["company_name"])){ if($_POST["company_name"] == $comp_name){ header("Location: http://www.hotmail.com"); exit(); } else{ header("Location: http://www.yahoo.com"); exit(); } } ?> The thing is i'm getting this error when i test it: Warning: Cannot modify header information - headers already sent by (output started at D:\Sites\killerphp.com\form_test.php:10) in D:\Sites\killerphp.com\form_test.php on line 17 Please can some one help me out, i'm sure this is just basic stuff but i just cant get it to work Cheers. i'm not sure how to ask this question on google, so i'm going to ask for your help. here's the code that i have the question about <form action='findMovie.php' method='post'> <table> <?php $result = mysql_query ("SELECT genre FROM genres ORDER BY genre"); while ($row = mysql_fetch_array($result)) { $genre = $row['genre']; echo "<tr><td>" .$genre ."</td><td><input type='hidden' name='" .$genre ."' value='" .$genre ."'><input type='submit' name='listMovies'></td></tr>"; } ?> </table> </form> so i have this form that creates a list of submits from a table that i have created. the form works perfectly fine (i realize the design is not that great... i'm just going for functionality now) what i need is to turn the value of the hidden field (which is dynamically created by a variable) into a variable in the handler so that I can search my movie table and get the movies by genre. does this make sense? and any help is greatly appreciated. i'm not a great programmer, but i do it in my spare time as a hobby. so go easy on my coding, it works and that's the most i'm concerned with at the moment. thanks ahead of time I'm researching ways that my server can be vulnerable. So far, I've strongly relied on regex to sanitize anything susceptible to user input/manipulation. Should I be trying other methods? Should I be changing input to html entities, even though they're bypassed w/ regex? Any recommendations on other methods to secure my server besides securing user input? |
