menios Posted December 1, 2007 Share Posted December 1, 2007 I ve been trying to display items from my product table but instead of selecting them by category id it just displays everything. I can't find what goes wrong. so here is the code if someone could help with <html> <body> <?php $rpp; //Records Per Page $cps; //Current Page Starting row number $lps; //Last Page Starting row number ///////////////////////////////////////////////////////////////////////////////// //Database connection ///////////////////////////////////////////////////////////////////////////////// $user="root"; $password="asere"; $database="smalltownbooks"; $tablename="tbl_product"; $conn=mysql_connect("localhost",$user,$password); mysql_select_db($database,$conn) or die( "Unable to select database"); mysql_query($sql,$conn); if (isset($_GET['1'])) { $cat = $_GET['1']; // for simplicity only. $sql = "SELECT * FROM tbl_product WHERE cat_id = '$cat'"; echo $sql or die ("dead"); } ///////////////////////////////////////////////////////////////////////////////// ///////////////////////////////////////////////////////////////////////////////// //Load for the first time First result printed user will click next to change ///////////////////////////////////////////////////////////////////////////////// if(empty($_GET["cps"])) { $cps = "0"; } else { $cps = $_GET["cps"]; } ///////////////////////////////////////////////////////////////////////////////// $a = $cps+1; $rpp = "15"; $lps = $cps - $rpp; //Calculating the starting row number for previous page ///////////////////////////////////////////////////////////////////////////////// //Check for previus link If the user is viewing the first set of data then the link will //be disabled, if on the next set then it will carry the $lps in its link and enable it if ($cps <> 0) { $prv = "<a href='cookery.php?cps=$lps'>Previous</a>"; } else { $prv = "<font color='cccccc'>Previous</font>"; } ///////////////////////////////////////////////////////////////////////////////// /////////////////////////////////////////////////////////////////////////////// $q="Select SQL_CALC_FOUND_ROWS * from tbl_product limit $cps, $rpp"; $rs=mysql_query($q) or die(mysql_error()); $nr = mysql_num_rows($rs); //Number of rows found with LIMIT in action $q0="Select FOUND_ROWS()"; $rs0=mysql_query($q0) or die(mysql_error()); $row0=mysql_fetch_array($rs0); $nr0 = $row0["FOUND_ROWS()"]; //Number of rows found without LIMIT in action ///////////////////////////////////////////////////////////////////////////////// //Check the user has reached thelast page of the items if (($nr0 < 50) || ($nr < 10)) { $b = $nr0; } else { $b = ($cps) + $rpp; } ///////////////////////////////////////////////////////////////////////////////// ?> <br> <table border="1" cellpadding="4" cellspacing="1" width="100%" align="center"> <tr><td bgcolor="#000080" align='Center'><b><font face="verdana" color="#FFFFFF">Title</font></b></td> <td bgcolor="#000080" align='Center'><b><font face="verdana" color="#FFFFFF">test</font></b></td> </tr> <?php while ($row=mysql_fetch_array($rs)) { ///////////////////////////////////////////////////////////////////////////////// //loop after fullfilling the above SQL criteria. ///////////////////////////////////////////////////////////////////////////////// $cps = $cps +1; $val=$row["pd_name"]; $val2=$row ["pd_price"]; $val3=$row ["cat_id"]; echo "<tr><td width='10%' align='center'><font face=verdana><img</font></td><td align='center'><font fave=verdana>$val $val2 $val3 </font></td></tr>"; } echo "<tr><td align='right' colspan=2>$prv"; //Check whether there is a Next link if not disable if ($cps == $nr0) { echo " | <font color='CCCCCC'>Next</font>"; } else { if ($nr0 > 5) { echo " | <a href='cookery.php?cps=$cps&lps=$lps'>Next </a>"; } } ?> </td> </tr> </table> </body> </html> Link to comment https://forums.phpfreaks.com/topic/79704-solved-can-someone-help/ Share on other sites More sharing options...
revraz Posted December 1, 2007 Share Posted December 1, 2007 Why are you calling your Query before you set the Select statement? Link to comment https://forums.phpfreaks.com/topic/79704-solved-can-someone-help/#findComment-403614 Share on other sites More sharing options...
menios Posted December 1, 2007 Author Share Posted December 1, 2007 I m quite new to php/mysql programming so i couldn't really give you a reason Do you think that i should set the SELECT statement first?and then query?

revraz Posted December 1, 2007 Share Posted December 1, 2007 Lets look at it from a logical view. If you do echo $a $a = 1 What would $a echo out? Nothing right, because you are not setting it until after you echo it. So you are doing a mysql query before you enter the parameters.
