PHP - Can I Do 2 While Loops For The Results Of 1 Select Statement?
here is some simple code for getting and displaying fata from a database
Code: [Select] $sql="SELECT * FROM messages WHERE m_id = '".$id."'"; $result = mysql_query($sql); <table border='0' cellspacing="4"> while($row = mysql_fetch_array($result)) { echo "<tr>"; echo "<th>Message</th>"; echo "</tr>"; echo "<tr>"; echo "<td>" . $row['message'] . "</td>"; echo "</tr>"; } now ive used that while loop to display those results how can i do that again without having a new SQL statement. i cant do 2 while loops because the first one has already got to the end of the amount of rows basically how can i have another while loop displaying those same results again?

(1) The correct mysql query for multiple rows
(2) The if/elseif/else to pull data from these rows, and process it based on the row data
I'm only pulling data where A=1 and B=1,2 -- so two possible entries there (call them B1 and B2). I need a php if statement to choose whether the output of B is one of two urls (b1=google,b2=bing). The actual script is far more complex, with more than just 1,2 from B. I've stripped all the excesses down to this one if/else issue and the db query. The output php doesn't matter here. And I can add more elseif once this problem is solved. <?php mysql_connect(localhost, $db_username, $db_password); @mysql_select_db($db_database) or die("No connection"); $query = "Select * FROM table WHERE column='stuff' AND parent='1,2' ORDER BY id DESC LIMIT 10"; $query_result = mysql_query($query); $num_rows = mysql_num_rows($query_result); mysql_close(); ?> <?php for($i=0; $i< $num_rows; $i++){ //start a loop $stuff = mysql_result($query_result, $i, "column"); $row = mysql_fetch_assoc($query_result, $i); if($row['parent'] == 1) { $url = 'http://google.com'; } else { $url = 'http://www.bing.com'; } ?>My own first attempt at a if/then was 500. I got help on another site to redo it (new code shown here), but the new if/else always show the else (Bing). It was also at this time that I learned that "1,2" only showed 1. Hoping that this site is far more friendly than StackOverflow. . Edited by kpmedia, 17 December 2014 - 07:22 PM. I have two tables...one is scheduled_umps and one is games. Both tables have a column 'game_id'. I need to select how many games a person is scheduled for in a given time frame. Here's what I have for the select...and it's not working (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 'WHERE scheduled_umps.ump_id = '34' AND games.game_id = scheduled_umps.game_id AN' at line 1) Code: [Select] <?php $today_is_this_date = date('Y-m-d'); $four_months_ago = date('Y-m-d', strtotime('-4 months', strtotime($today_is_this_date))); $four_months_from_now = date('Y-m-d', strtotime('+4 months', strtotime($today_is_this_date))); /// How many games have you worked? //$query = "SELECT COUNT(ump_id) FROM scheduled_umps WHERE `ump_id` = '$_SESSION[ump_id]'"; ///this one selects how many games you've worked NO MATTER WHAT THE DATE $query = "SELECT scheduled_umps.game_id, games.game_id, COUNT(scheduled_umps.ump_id) WHERE scheduled_umps.ump_id = '$_SESSION[ump_id]' AND games.game_id = scheduled_umps.game_id AND games.game_id BETWEEN $four_months_ago AND $four_months_from_now"; $result = mysql_query($query) or die(mysql_error()); while($row = mysql_fetch_array($result)){ echo "You have been scheduled on <b>". $row['COUNT(ump_id)'] ."</b> dates for the $_SESSION[association_name]."; } ?> [\code] Any ideas where I'm going wrong? Thanks for the help...I HATE multi-table selects! Hi All, I have the following Query: Code: [Select] $query = 'SELECT `BookingID`,`OfferID`, `name`, `OfferCount`,`OfferPrice` FROM `Offers_Finance` JOIN offers_details ON `OfferID` = `o_d_id` WHERE `BookingID` ="' .$bookerid. '"'; if ( !$result = $mysqli->query( $query ) ) { die( $mysqli->error ); } $field = $result->fetch_object(); This will return anywhere between 0 and 50 Rows of Data. For Each Row returned, I want to do the following: Quote echo '<tr>'; echo '<td>' . $field->name.'</td>'; echo '<td></td>'; echo '<td>£' . $field->OfferPrice.'</td>'; echo '<td></td>'; echo '<td>' . $field->OfferCount . '</td>'; echo '<td></td>'; echo '<td>£' . $field->OfferPrice * $field->OfferCount . '</td>'; echo '</td>'; echo '</tr>'; The problem I have is - how do I loop through the results returned from the query to output multiple rows? Sorry if this doesn't make much snese, I'm new to PHP and the whole web development world, but have been landed with finishing a project someone else started! If someone would be kind enough to turn this into a working example, it would help no end as I have about 20 of these things to figure out across the project! I have a Select statement that relies on two session variables to complete the statement. One variable, $egroup, supplies a column name. I cannot make the SELECT work. It works fine if I substitute the real name of one of the columns such as "egroup1", or "egroup6", but that's what the variable $egroup is for. Can anyone tell me where I'm wrong? I guess the answer is in the syntax, but I'm not very good at this and I've been on it for too long. Any help gratefully taken. Code: [Select] <?php $query1 = mysql_query("SELECT * FROM topics WHERE managerId='".$managerId."' AND "$egroup"= 1 ORDER BY title ASC"); ?> $sql=mysql_query("SELECT * FROM `buds` WHERE `level`<='$user_level' UNION SELECT * FROM `buds`, `unlocked_buds` WHERE buds.`id` = unlocked_buds.`bud_id` ORDER BY buds.`id` ASC") or die("A MySQL error has occurred.<br />Your Query: " . $sql . "<br /> Error: (" . mysql_errno() . ") " . mysql_error()); I have been trying to learn about UNION select statements. I ran the query above and got this response: Quote Error: (1222) The used SELECT statements have a different number of columns I think I know what the problem is, but not sure how to fix it. There is two columns, one is "buds" which holds the flowers seeds info. The seconds is "unlocked_buds" which just links the "id" from buds to "user_id" to the user table. Both buds and unlocked_buds are both 8 columns. What do I need to learn? Hey guys, I'm trying to get this working...

I am new to this. I figured out how to an INSERT with an example, but now I need to fetch an ID and cannot get it to work. Any help much obliged. All I need is just one good example. Looked all over the place, but all I get are insert examples, which is NOT what i need. Really need one with a select and fetch. This topic has been moved to MySQL Help. http://www.phpfreaks.com/forums/index.php?topic=327011.0 I have got a set of data for a country for each week of the year, but want to display the data a quarter at a time, using a form which posts a value into LIMIT, which was OK for the 1st quarter, but for subsequent quarters I needed to use LIMIT in the form LIMIT start, rows.

Hi Guys I don't know if this is possible but can someone point me in the right direction. I have a php function which takes two inputs and returns an output. for simplicity's sake let's say it's an addition function. What I want to do is use a mysql select statement to show all the rows from a database where field1 and field2 equal '3'. Here's the sort of thing I mean. function addNumbers($one,$two) { return $one + $two; } mysql_query("SELECT * FROM table WHERE 'addNumbers(field1,field2)' = '3'"); What I actually want to do is a lot more complex than this but I am trying to understand how to make the syntax work in simple terms first.
