PHP - Turning Sql Into A Query
having a problem turning this sql into a query and I need it to only update rows where id field is empty.
Code: [Select] UPDATE systems SET naqahdah = naqahdah + naqahdah_mines * 2 I tried this out with failure Code: [Select] <?php mysql_query("UPDATE systems SET naqahdah= naqahdah + naqahdah_mines * 2 WHERE id <> ' ' "); ?> so i tried getting rid of WHERE and couldnt even get this to work. I tested the sql out it works fine. Code: [Select] <?php mysql_query("UPDATE systems SET naqahdah= naqahdah + naqahdah_mines * 2 "); ?> Similar TutorialsHey i'm having trouble figuring out how to do this. This is the code grabbing the users who are online and listing them one by one. Code: [Select] $qt=mysql_query("SELECT username FROM users WHERE lastvisit > '$tm' and online='ON'"); echo mysql_error(); while($nt=mysql_fetch_array($qt)){ echo "<tr><td> $nt[username] </td></tr>"; } ?> what i want to do is have each username be a hyperlink that links to their profile how would i go about this? cause i'm completely clueless on this. is there some way i can do it in the php or will i need to make a varchar column for each player that holds their profile link and grab that with the query too? I am trying to turn a .txt file into an array, count the items in the array, and display a random quote from it.
<p class = "center">
<?php
$Proverb = file('../proverbs.txt');
$ProverbCount = count($Proverb);
echo rand(0, $ProverbCount-1);
?>

I got a tab menu, where the user choose his category and a list of sub categories appear. Personally I like the old fashion way, where everything listed like in craiglist.com ... How can I turn the following tab menu, into a simple 3 column list? <!--CATEGORIES--> <div id="selCategories"> <div class="slidetabsmenu menu_fix"> <ul> <?php if(isset($groups) and $groups->num_rows()>0) { $i=0; foreach($groups->result() as $group) { ?> <li id="gr<?php echo $i;?>" class="<?php if($i == '0') echo "selected"; ?>"><a href="javascript:;" onclick="getCat('<?php echo $i ?>','<?php echo $groups->num_rows ?>',<?php echo $group->id;?>);"><span><?php echo $group->group_name;?></span></a></li> <?php $i++;} } ?> </ul> </div> <div class="clsInfoBox"> <div class="block"> <div class="grey_t"> <div class="grey_r"> <div class="grey_b"> <div class="grey_l"> <div class="grey_tl"> <div class="grey_tr"> <div class="grey_bl"> <div class="grey_br"> <div class="cls100_p"> <h4><span class="clsCategory"><?php echo $this->lang->line('CATEGORIES');?></span></h4> <div class="clsCategoryList clearfix" id="catInner"> </div> </div> </div> </div> </div> </div> </div> </div> </div> </div> </div> </div> </div> <!--END OF CATEGORIES--> Your tips, directions, and support is highly appreciated. Hi, I'm pretty new to PHP, struggled my way through most of my encounters with PHP so far, but getting the hang of it I'm looking for a simple script that turns a number or word served by a weather station into a graphic. E.g. If the temp is 20 degrees, a graphic I've designed would be shown, or a cloud or the sun or whatever. At the moment the weather station feed is converted from 'webtags' in to php tags (temp is $temp, wind is $wind etc.) and these echo out as numbers and words on the website. I can sort of see how it would work in my head, but need a little help. Can anyone please point me in the right direction? Thanks (for reference site is www.southtyneweather.co.uk) I recently had a need to check several arrays, and if an index wasn't set, set a variable to a given value. The code was such that I couldn't perform the isset check all at once. I then thought "wouldn't it be great if I could try the script, and catch the error or warning". Searching a bit, I came across the following script. I am a little nervous, however, that there might be negative consequences of doing so. Thoughts?
set_error_handler(function($errno, $errstr, $errfile, $errline, array $errcontext) {
// error was suppressed with the @-operator
if (0 === error_reporting()) {
return false;
}
throw new ErrorException($errstr, 0, $errno, $errfile, $errline);
});
try {
dns_get_record();
} catch (ErrorException $e) {
// ...
}
right now i have my date system to say "X amount of seconds ago, X hours ago, X days ago, X years ago, How could i turn mktime() (1290874161) into a mm/dd/yyyy format? so it would say like, "Nov 27, 2010 at Hour:Minute" (whatever the hour/minute is) Hi guys, I have written a page that contains a form. When the user chooses a color, it is posted, then the posted value is re-written as a filename, sent through a function, and the image on the page uses the "colorized.gif" created by the function to make an image swap "onclick. Problem is, no matter the choice, it always changes the picture to orange! Here is the code for the form: <?php include('function.php'); ?> <!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> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>PHP GD CONFIGURATOR</title> </head> <body> <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post"> Red<input type="radio" name="color" value="red" /> Orange<input type="radio" name="color" value="orange" /> Ivory<input type="radio" name="color" value="ivory" /> Black<input type="radio" name="color" value="black" /> <input type="submit" name="submit" value="submit" /> </form> <?php if($_POST['color'] != NULL){ echo $_POST['color']; $file =('gdimages/' . $_POST['color'] . '.gif'); createImg($file); } ?> <img src="default.jpg" name="lola" alt="lola dining chair" onclick="this.src = 'colorized.gif'" /> </body> </html> And here is the function... function createImg ($imgname1) { $base = imagecreatefromgif("gdimages/base.gif"); $top = imagecreatefromgif($imgname1); if ($top) { imagecopy($base, $top, 0, 0, 0, 0, 250, 250); imagejpeg($base, 'colorized.gif'); imagedestroy($base); } else{ header("Content-Type: text/html"); } } I really can't understand it...this is my first attempt at programming something new by myself...and I really need it to work!!! I also plan for this to work with combining more than 2 images from more than two choice menus...so debugging now is definitely necessary. Any suggestions? i run several wordpress on domains - and wthin the wordpress i have a plugin that allows uploads of images -within a certain plugin the interesting thing: image upload is - sometimes possible and sometinmes impossible: see here the circumstances - PHP Version : 5.3.28 PHP Safe Mode : On image upload is impossible - and on the same server - a second vhost PHP Version : 5.3.28 PHP Safe Mode : off image upload is possible why is this so - does it have to do with the safe-mode - I have got a date field in my mysql database with events, and as you know date in MYSQL uses yyyy/mm/dd but I would first like to turn this around to dd/mm/yyyy but also turn this into for example "Tuesday - May 1990" would anyone like to point me into the right direction? Much appreciated! I know I'm doing it something right, but can someone tell me why only one table is showing up? Can you help me fix the issue? Heres my code: function showcoords() { echo"J3st3r's CoordVision"; $result=dbquery("SELECT alliance, region, coordx, coordy FROM ".DB_COORDFUSION.""); dbarray($result); $fields_num = mysql_num_fields($result); echo "<table border='1'>"; // printing table headers echo "<td>Alliance</td>"; echo "<td>Region</td>"; echo "<td>Coord</td>"; // printing table rows while($row = mysql_fetch_array($result)) { // $row is array... foreach( .. ) puts every element // of $row to $cell variable foreach($row AS $Cell) echo "<tr>"; echo "<td>".$row['alliance']."</td>\n"; echo "<td>".$row['region']."</td>\n"; echo "<td>".$row['coordx'].",".$row['coordy']."</td>\n"; echo "</tr>\n"; } echo "</table>"; mysql_free_result($result); } I have 2 rows inserted into my coords table. Just frustrated and ignorant to php. Here is my code: // Start MySQL Query for Records $query = "SELECT codes_update_no_join_1b" . "SET orig_code_1 = new_code_1, orig_code_2 = new_code_2" . "WHERE concat(orig_code_1, orig_code_2) = concat(old_code_1, old_code_2)"; $results = mysql_query($query) or die(mysql_error()); // End MySQL Query for Records This query runs perfectly fine when run direct as SQL in phpMyAdmin, but throws this error when running in my script??? Why is this??? Code: [Select] You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '= new_code_1, orig_code_2 = new_code_2WHERE concat(orig_code_1, orig_c' at line 1 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!

If you also have any feedback on my code, please do tell me. I wish to improve my coding base. Basically when you fill out the register form, it will check for data, then execute the insert query. But for some reason, the query will NOT insert into the database. In the following code below, I left out the field ID. Doesn't work with it anyways, and I'm not sure it makes a difference. Code: Code: [Select] mysql_query("INSERT INTO servers (username, password, name, type, description, ip, votes, beta) VALUES ($username, $password, $name, $server_type, $description, $ip, 0, 1)"); Full code: Code: [Select] <?php include_once("includes/config.php"); ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title><? $title; ?></title> <meta http-equiv="Content-Language" content="English" /> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <link rel="stylesheet" type="text/css" href="style.css" media="screen" /> </head> <body> <div id="wrap"> <div id="header"> <h1><? $title; ?></h1> <h2><? $description; ?></h2> </div> <? include_once("includes/navigation.php"); ?> <div id="content"> <div id="right"> <h2>Create</h2> <div id="artlicles"> <?php if(!$_SESSION['user']) { $username = mysql_real_escape_string($_POST['username']); $password = mysql_real_escape_string($_POST['password']); $name = mysql_real_escape_string($_POST['name']); $server_type = mysql_real_escape_string($_POST['type']); $description = mysql_real_escape_string($_POST['description']); if(!$username || !$password || !$server_type || !$description || !$name) { echo "Note: Descriptions allow HTML.

For example, if I do Code: [Select] $sql = 'My query'; $rs = mysql_query($sql, $mysql_conn); Is it then possible to run a second query on this data such as Code: [Select] $sql = 'My query'; $secondrs = mysql_query($sql, $rs, $mysql_conn); Thanks for any help I'm trying to update every record where one field in a row is less than the other. The code gets each row i'm looking for and sets up the query right, I hope I combined the entire query into one string each query seperated by a ; so it's like UPDATE `table` SET field2= '1' WHERE field1= '1';UPDATE `table` SET field2= '1' WHERE field1= '2';UPDATE `table` SET field2= '1' WHERE field1= '3';UPDATE `table` SET field2= '1' WHERE field1= '4';UPDATE `table` SET field2= '1' WHERE field1= '5'; this executes properly if i run the query in phpMyAdmin, however when I run the query in PHP, it does nothing... Any advice? Say I have this query: site.com?var=1 ..I have a form with 'var2' field which submits via get. Is there a way to produce: site.com?var=1&var2=formdata I was hoping there would be a quick way to affix, but can't find any info. Also, the query could sometimes be: site.com?var2=formdata&var=1 I would have to produce: site.com?var2=updatedformdata&var=1 Is my only option to further parse the query? What would be the correct way to close a mysql query? At current the second query below returns results from the 1st query AND the 2nd query The 3rd query returns results from the 1st, 2nd and 3rd query. etc etc. At the moment I get somthing returned along the lines of... QUERY 1 RESULTS Accommodation 1 Accommodation 2 Accommodation 3 QUERY 2 RESULTS Restaurant 1 Restaurant 2 Restaurant 3 Accommodation 1 Accommodation 2 Accommodation 3 QUERY 3 RESULTS Takeaways 1 Takeaways 2 Takeaways 3 Restaurant 1 Restaurant 2 Restaurant 3 Accommodation 1 Accommodation 2 Accommodation 3 Code: [Select] <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <?php include($_SERVER['DOCUMENT_ROOT'].'/include/db.php'); ?> <title>Untitled Document</title> <style type="text/css"> <!-- --> </style> <link href="a.css" rel="stylesheet" type="text/css" /> </head><body> <div id="listhold"> <!------------------------------------------------------------------------------------------------------------------------------------------------------> <div class="list"><a href="Placestostay.html">Places To Stay</a><br /> <?php $title ="TITLE GOES HERE"; $query = mysql_query("SELECT DISTINCT subtype FROM business WHERE type ='Accommodation' AND confirmed ='Yes' ORDER BY name"); echo mysql_error(); while($ntx=mysql_fetch_row($query)) $nt[] = $ntx[0]; $i = -1; foreach($nt as $value) {$i++; $FileName = str_replace(' ','_',$nt[$i]) .
