PHP - Problem With Searching Returned Query Results
Search not functioning. The drop down box to search on Club_Name and Email is blank, clicking search results unchanged ... all suggestions appreciated ... newbie at php. Thanks.

I have it working so far so good, but the last part I can't seem to get working. I have it so all the products that have the desired category are displayed, but I want a more detailed analysis of the product to appear when the image is clicked, which at the moment, displays a blank page. http://www.webwib.co...?p=floorpuzzles - this is the hand coded version that demonstrates how I want it to work. http://www.webwib.co...hp?floorpuzzles - this is the db version so far, it works how it is intended to apart from the last stage, which returns as a blank page rather than a dedicated page for the selected product. Here is my code, the third segment beginning with "if(isset($_GET['$ID'])){", is my attempt at the final stage.

Hi guys, I am working with an old script at the moment, there is one page which just will not populate the table results. I have tried running multiple debugging commands but the only one it flags is the line displaying Quote last; saying it's not a used function. If I comment out this line, no errors are produced but the results do not enter the table. Can anyone shed some light on this please, I've spent hours and hours and banging my head against a brick wall would probably be more constructive right now. Many thanks indeed for any help or advice. <?php mysql_connect("localhost", "$db_user","$db_upwd") or die ("Error - Could not connect: " . mysql_error()); mysql_select_db("$database"); $query="select host,count(*) from badc_mis_prog group by host"; $result = mysql_query($query) or die ("Error - Query: $query" . mysql_error()); $count=0; $hosts=array(); while ($row = mysql_fetch_array($result, MYSQL_NUM)) { $html_hlname=$row[0]; $html_hlname=preg_replace("/</","<",$html_hlname); $html_hlname=preg_replace("/>/",">",$html_hlname); array_push($hosts, $html_hlname,$row[1],0); $count++; } $query="select host,count(*) from badc_mis_prog where reported=1 group by host"; $result = mysql_query($query) or die ("Error - Query: $query" . mysql_error()); while ($row = mysql_fetch_array($result, MYSQL_NUM)) { $html_hlname=$row[0]; $html_hlname=preg_replace("/</","<",$html_hlname); $html_hlname=preg_replace("/>/",">",$html_hlname); for ($i=0; $i<($count*3); $i+=3) { if ($hosts[$i] == $html_hlname) { $hosts[($i+2)]=$row[1]; last; } } } for ($i=0 ; $i<(($count-1)*3); $i+=3){ for ($j=$i+3 ; $j<($count*3); $j+=3){ if ($hosts[($i+1)] < $hosts[($j+1)]){ $temp=array(); $temp[0]=$hosts[$i]; $temp[1]=$hosts[($i+1)]; $temp[2]=$hosts[($i+2)]; $hosts[$i]=$hosts[$j]; $hosts[($i+1)]=$hosts[($j+1)]; $hosts[($i+2)]=$hosts[($j+2)]; $hosts[$j]=$temp[0]; $hosts[($j+1)]=$temp[1]; $hosts[($j+2)]=$temp[2]; } } } print "<br><br><br><center><table border=\"1\">\n"; print "<tr><td>Host Name</td><td>Hosted</td><td>Reported</td><td>Ratio H/R</td></tr>\n"; for ($i=0; $i<($count*3); $i+=3) { if ($hosts[($i+1)]<15){ break;} printf ("<tr><td> %s </td><td> %d </td><td> %d </td><td>%.1f %%</td></tr>\n",$hosts[$i],$hosts[($i+1)],$hosts[($i+2)],(($hosts[($i+2)]/$hosts[($i+1)])*100)); } print "</table></center>\n"; ?> Greetings!

I am interested in taking a result returned from a database and having it displayed in a certain way/style on the user's screen; For example, the user enters text into a field and hits "submit" - the data is saved in the database then displayed to the user (This part I have working just fine so far due to help I received here.) My question is if I would like to, for example, have said text not simply dumped to the top of the screen, inline, but nicely formatted in a boxed, text area, I assume I will use HTML/CSS, and I was wondering if anyone had any good links/tutorials regarding this topic so I may look further into it (my search thus far has not turned up the correct topic or results). Thank-you in advance for any assistance. ~Matty I've had a bit of a search around to see if this is possible but have yet to find something. I'm looking to be able to offset the results from opendir or similar function without returning all the files/folders. In other words i'd like to display the file/folder results over multiple pages when there are a lot of files/folders to display. Is this at all possible? I am looking to accomplish the following but have been hitting a brick wall: * User enters a single keyword into a text field, and conducts a search keyword search. * The results are pulled from the campusbooks.com API(API docs attached) * result are then output in <div> class and includes all the book details and its corresponding url./img etc I'm trying to simplify this process but I continue to receive syntax errors. A step by step practical explanation would do me justice! Am currently using this code, and actually thinking about it should split the query to an include in order to allow for other database drivers, on the chance we may decide to ditch the old MySQL. But I digress from the question. Code: [Select] include($lib."dbconfig.php"); $q = 'SELECT * FROM file WHERE this = "'.$that'"; $result = mysql_query($q); if (mysql_num_rows($result) > 0) If the query doesn't pick up a row I'm getting this error yo, Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in D:\webpages\*\*\admin.php on line 553 So what would be a better way of testing if the query was successful? Have a web page that displays a number of update forms depending on the amout of records that get returned from a mysql query, if query returns 4 records then the page will display 4 identical forms, the trouble i'm having is getting the each of the 4 forms to display a different record as at the moment they all show just first record of query. I have played around with loops but not getting anywhere which may be due to my limited knowledge code for page is below Code: [Select] <?php $numberofrow =mysql_num_rows($Recordset1); for($counter = 1;$counter<=$numberofrow;$counter++){ ?> <label for="hometeam2"></label> <form id="form1" name="form1" method="POST" action="<?php echo $editFormAction; ?>"> <label for="hometeam"></label> <input name="fixid" type="text" id="fixid" value="<?php echo $row_Recordset1['FixtureID']; ?>" /> <input name="hometeam" type="text" id="hometeam2" value="<?php echo $row_Recordset1['hometeamname']; ?>" /> <label for="homescore"></label> <input name="homescore" type="text" id="homescore" value="<?php echo $row_Recordset1['homescore']; ?>" /> <label for="awayscore"></label> <label for="fixid"></label> <input name="awayscore" type="text" id="awayscore" value="<?php echo $row_Recordset1['awayscore']; ?>" /> <label for="awayteam"></label> <input name="awayteam" type="text" id="awayteam" value="<?php echo $row_Recordset1['awayteamname']; ?>" /> <input type="submit" name="update" id="update" value="Submit" /> <input type="hidden" name="MM_update" value="form1" /> i basically have a php search form on a property website, and depending on what area/type of property/number of bedrooms and price range the search form should bring up results based on that. at the moment it just bring up everything. how would i make it bring up the correct results depending on the search made? here my php code: Code: [Select] <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Mumtaz Properties</title> <link rel="stylesheet" href="cutouts/style.css"/> </head> <body> <!--Main Div Tag--> <div id="wrapper"> <div id="header"> <div id="logo"><a href="index.html"><img src="cutouts/Homepage/logo.png" alt=""/></a></div> </div> <div id="navigation"> <a id="Home" href="index.html" title="home"><span>home</span></a> <a id="Sale" href="forsale.html" title="for sale"><span>for sale</span></a> <a id="Rent" href="forrent.html" title="for rent"><span>for rent</span></a> <a id="Contact" href="contact.html" title="contact us"><span>contact us</span></a> </div> <div id="main"> <div id="results"><img src="cutouts/Homepage/results.png"></div> <?php $server = ""; // Enter your MYSQL server name/address between quotes $username = ""; // Your MYSQL username between quotes $password = ""; // Your MYSQL password between quotes $database = ""; // Your MYSQL database between quotes $con = mysql_connect($server, $username, $password); // Connect to the database if(!$con) { die('Could not connect: ' . mysql_error()); } // If connection failed, stop and display error mysql_select_db($database, $con); // Select database to use // Query database $result = mysql_query("SELECT * FROM Properties"); if (!$result) { echo "Error running query:<br>"; trigger_error(mysql_error()); } elseif(!mysql_num_rows($result)) { // no records found by query. echo "No records found"; } else { $i = 0; echo '<div style="font-family:helvetica; font-size:14px; padding-left:15px; padding-top:20px;">'; while($row = mysql_fetch_array($result)) { // Loop through results $i++; echo '<img class="image1" src="'. $row['images'] .'" />'; //image echo "<span style=\"color:#63be21;\">Displaying record $i<br>\n<br></span>"; echo "<b>Location:</b> ". $row['Location'] .

Say I do a query from a database that only asks for one field in return (which always has a number in it). How do you write the PHP to take the first number returned and add it to the next number returned (NOTE: There may be more than two numbers returned, but for now, I'm always dealing with two) For example, say I do a query that returns the number 27 first and then the number 10 second. FYI, these numbers will be available in the variable $diff['result']. So the code after the query would look something like this, but obviously i'm struggling with the part in comments... Code: [Select] if (!$numbers) { die("Database query failed: " . mysql_error()); } else { while ($diff = mysql_fetch_array($numbers)) { //this would bring back 27 first, in the variable $diff['result'] and then on the 2nd loop through, it would bring back 10 in the $diff['result'] variable //ultimately, i just want the difference between the numbers (which in the case would be 17). It's just a simple addition, so Im obviously an idiot because I can't figure out the syntax for adding the first returned number to the next returned number:) } } I'm trying to develop some php that will execute a MySQL query and move the results into XML. In this particular instance, only one record is expected to be returned, and that one row will contain all the customer data, such as last name, first name, address1, etc. While I can get my code to work and create the xml if I hard-code in all the keys (MySQL column names), I would like it to dynamically step through all the keys/MySQL column names so that if the db changes later (add more columns, for instance) the code generating the XML won't need to be altered. It should take the MySQL column name, create an element based on the column name, then create a text node and insert the value. Currently I'm just at the spot of testing by echoing the appropriate key/value pairs. The code is stopping after the first key/value without going through the rest of the columns. What do I need to do in order to get it to dynamically step through each column and get the key/value? Here's the relevant code: if($_POST['buscode']) {echo "buscode is: ".$_POST['buscode']."<HR>";} else {echo "ERROR WITH RETRIEVING BUSCODE<HR>";} $buscode = $_POST['buscode']; $query = "SELECT * " ."FROM customers " ."WHERE buscode = '$buscode'"; echo "Query will be: ".$query."<HR>"; $result = mysql_query($query); if($result){echo "Success retrieving data from ats_ajax.<HR>";} else{echo "Error retrieving data from ats_ajax\; MySQL error is:".mysql_error($result)."<HR>";} //////////////////////////////////////// // Let's test getting the keys and values from the array.... /////////////////////////////////////// while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) { echo "This is step ".$i."<BR>"; $key = key($row); echo "Key is: ".$key."<BR>"; echo "Value is: ".$row[$key]."<BR>"; $i++; }//close of while Hello folks,
In trying to improve the user experience for my first WebApp I have decided to create two new tables - one a master file to contain a list of all stores, and the second a master file to contain a list of all products that are normally purchased - and I would like to use the values from these two tables as lookup values in dropdown listboxes, to which the user can also add new entries.
As it turns out, I'm stuck on the very first objective i.e. to lookup/pull-in the distinct values from the master tables.
The problem I'm having is that the query seems to return no rows at all...in spite of the fact that there a records in the table, and the exact same query (when run within the MySQL environment) returns all the rows correctly.
Is there something wrong with my code, or how can I debug to see whether or not the query is being executed?
Objective # 2, which is to allow new values to be entered into the dropdown listbox, and then inserted into the respective table is certainly waaay beyond my beginner skills, and I'll most certainly need to some help with that as well..so if I can get some code/directions in that regard it will be most appreciated.
Thank you.

I have a search page and everything works fine but I would like to add the latest 10 rows to the page so there is something to look at or click on before the user searches. The page is at: www.giantstridedives.com/locations. You can see that it's pretty boring. Hit submit and you'll see the entries so far (only 3 right now). I'd like to have the latest 10 display there by default but then when a user searches they are replaced by the search results. Make sense? Here's the code I'm using for the search: Code: [Select] <?php if (isset($_POST['submit'])) { require_once('dbconnection.php'); mysqli_select_db($conn, $dbname); $searchterm = $_POST['search']; $searchterm = strip_tags($searchterm); $searchterm = trim ($searchterm); $q ="SELECT * FROM locations WHERE loc_name LIKE '%" . $searchterm . "%' AND loc_approved != '0'"; $r = mysqli_query($conn, $q) or die(mysql_error($q)); $row = mysqli_fetch_assoc($r); $rowcount = mysqli_num_rows($r); } ?> <h1>Search for Scuba Dive Locations</h1> <form id="searchform" name="searchform" method="post" action="index.php"> <input type="text" name="search" id="search_bar" /> <input type="submit" name="submit" id="submit" value="Submit" /> </form> <span style="color: #333;">Search for the name of the location, ie: Devils Den or USS Oriskany.</span><br /> <?php if (isset($_POST['submit'])) { if ($rowcount == 0) { echo "Sorry, but we can not find an entry to match your query: <strong>$searchterm</strong>"; } else { //this tells the table below to display since $totalRows_Products_res is not 0 ?> <table style="font-size: 14px;" border="0" width="650"> <tr> <td colspan="6"><p>You searched for <strong><?php echo $searchterm; ?></strong>. Results are displayed below.</p></td> </tr> <tr> <td><strong>Location Name</strong></td> <td><strong>City</strong></td> <td><strong>State</strong></td> <td><strong>Depth (ft)</strong></td> <td><strong>Fees</strong></td> <td><strong>Gear Rentals</strong></td> <td><strong>Map</strong></td> </tr> <?php do { ?> <tr> <td><a href="loc_details.php?loc_id=<?php echo $row ['loc_id']; ?>"> <?php echo $row ['loc_name']; ?> </a></td> <td><?php echo $row ['loc_city']; ?></td> <td><?php echo $row ['loc_state']; ?></td> <td><?php echo $row ['loc_depth']; ?></td> <td>$<?php echo $row ['loc_fee']; ?></td> <td><?php if($row['loc_gear'] == 1) { echo 'Yes'; } else { echo 'No'; } ?></td> <td><a href="http://maps.google.com/maps?q=<?php echo $row ['loc_lat'];?>,<?php echo $row ['loc_lon'];?>" target="_blank">View Map</a></td> </tr> <?php } while ($row = mysqli_fetch_assoc($r)); ?> </table> <?php mysqli_free_result($r); } // this closes out results else } ?> I figure I can use the below query to get the results. Code: [Select] select * from table WHERE id > ((SELECT MAX(id) from table) - 10);I'm just not sure how I can display them by default and then have them be replaced by the search results. Anyone have any ideas for me? As always I appreciate the help as I continue to learn this beast. Hello all,
Based on the suggestion of you wonderful folks here, I went away for a few days (to learn about PDO and Prepared Statements) in order to replace the MySQLi commands in my code. That's gone pretty well thus far...with me having learnt and successfully replaced most of my "bad" code with elegant, SQL-Injection-proof code (or so I hope).
The one-and-only problem I'm having (for now at least) is that I'm having trouble understanding how to execute an UPDATE query within the resultset of a SELECT query (using PDO and prepared statements, of course).
Let me explain (my scenario), and since a picture speaks a thousand words I've also inlcuded a screenshot to show you guys my setup:
In my table I have two columns (which are essentially flags i.e. Y/N), one for "items alreay purchased" and the other for "items to be purchased later". The first flag, if/when set ON (Y) will highlight row(s) in red...and the second flag will highlight row(s) in blue (when set ON).
I initially had four buttons, two each for setting the flags/columns to "Y", and another two to reverse the columns/flags to "N". That was when I had my delete functionality as a separate operation on a separate tab/list item, and that was fine.
Now that I've realized I can include both operations (update and delete) on just the one tab, I've also figured it would be better to pare down those four buttons (into just two), and set them up as a toggle feature i.e. if the value is currently "Y" then the button will set it to "N", and vice versa.
So, looking at my attached picture, if a person selects (using the checkboxes) the first four rows and clicks the first button (labeled "Toggle selected items as Purchased/Not Purchased") then the following must happen:
1. The purchased_flag for rows # 2 and 4 must be switched OFF (set to N)...so they will no longer be highlighted in red.
2. The purchased_flag for row # 3 must be switched ON (set to Y)...so that row will now be highlighted in red.
3. Nothing must be done to rows # 1 and 5 since: a) row 5 was not selected/checked to begin with, and b) row # 1 has its purchase_later_flag set ON (to Y), so it must be skipped over.
Looking at my code below, I'm guessing (and here's where I need the help) that there's something wrong in the code within the section that says "/*** loop through the results/collection of checked items ***/". I've probably made it more complex than it should be, and that's due to the fact that I have no idea what I'm doing (or rather, how I should be doing it), and this has driven me insane for the last 2 days...which prompted me to "throw in the towel" and seek the help of you very helpful and intellegent folks. BTW, I am a newbie at this, so if I could be provided the exact code, that would be most wonderful, and much highly appreciated.
Thanks to you folks, I'm feeling real good (with a great sense of achievement) after having come here and got the great advice to learn PDO and prepared statements.
Just this one nasty little hurdle is stopping me from getting to "end-of-job" on my very first WebApp. BTW, sorry about the long post...this is the best/only way I could clearly explaing my situation.
Cheers guys!

What would be the correct way to close a mysql query?
