candice Posted September 15, 2008 Share Posted September 15, 2008 Hi, we are student's doing a web portal service. Initially we did all the codes in Mysqli, but now we need to change them to mysql. these are the problem we faced from the transitions. As you can see from the image, this is the correct result that we did in Mysqli http://www.flickr.com/photos/75437207@N00/2859928462/ but after we change the codes to mysql, we did a little amendments, we successfully able to retrieve the personal information from the database. http://www.flickr.com/photos/75437207@N00/2859099589/in/photostream/ But we still faced two problems. - unable to retrieve the images - under "who is in" they sld retrieve different name of staff from the database instead of the same keep repeating. <this is the mysql code from where we changed and where the 2 problems are> <?php session_start(); echo $name; echo $staffid; ob_start(); ?> <html> <head> <title>Staff Signage</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <link href="style.css" rel="stylesheet" type="text/css"> <script type="text/JavaScript"> <!-- function MM_preloadImages() { //v3.0 var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array(); var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++) if (a[i].indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}} } function MM_swapImgRestore() { //v3.0 var i,x,a=document.MM_sr; for(i=0;a&&i<a.length&&(x=a[i])&&x.oSrc;i++) x.src=x.oSrc; } function MM_findObj(n, d) { //v4.01 var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) { d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);} if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n]; for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document); if(!x && d.getElementById) x=d.getElementById(n); return x; } function MM_swapImage() { //v3.0 var i,j=0,x,a=MM_swapImage.arguments; document.MM_sr=new Array; for(i=0;i<(a.length-2);i+=3) if ((x=MM_findObj(a[i]))!=null){document.MM_sr[j++]=x; if(!x.oSrc) x.oSrc=x.src; x.src=a[i+2];} } //--> </script> <style type="text/css"> <!-- a:link { color: #000000; text-decoration: none; } a:visited { text-decoration: none; color: #000000; } a:hover { text-decoration: underline; color: #333333; } a:active { text-decoration: none; } --> </style></head> <body leftmargin="0" topmargin="0" marginwidth="0" marginheight="0" onLoad="MM_preloadImages('images/icons/rolloverProfile.jpg','images/icons/rolloverStatus.jpg','images/icons/rolloverStatusOut.jpg','images/icons/rollovereditImage.jpg')"> <!-- ImageReady Slices (main1.psd) --> <table width="800" height="600" border="0" align="center" cellpadding="0" cellspacing="0" id="Table_01"> <tr> <td width="800" height="136"><?php include("include/header.php") ?></td> </tr> <tr> <td width="800" height="438" valign="top" bgcolor="#FFFFFF"> <table width="795" height="426" border="0"> <tr> <td width="10" height="2"></td> <td width="762"></td> <td width="10"></td> </tr> <tr> <td height="409"></td> <td valign="top" bgcolor="#FFFFFF"><?php $staffid=$_SESSION['staffid']; require 'staffSql.php'; //connect to the database //$mysql = mysql_connect($DATABASE_SERVER, $DATABASE_USERNAME, $DATABASE_PASSWORD) or die(mysql_error()); mysql_connect ($dbhost, $dbusername, $dbuserpass); //select the database //mysql_select_db($DATABASE_NAME ); mysql_select_db($dbname) or die('Cannot select database'); //assign the data passed from Flex to variables $_SESSION['staffid'] = $staffid; //Query the database to see if the given username/password combination is valid. $query = "Select * from staff where staffid = '$staffid'"; $result = mysql_query($query); while ($row = mysql_fetch_array ($result)) { $name=$row['name']; $contactNo=$row['contactNo']; $ext=$row['ext']; $position=$row['position']; $photo=$row['photo']; $email=$row['email']; $status=$row['status']; echo'<table width="769" height="426" border="0">'; echo' <tr>'; echo' <td width="9" height="2"></td>'; echo' <td width="735"></td>'; echo' <td width="11"></td>'; echo' </tr>'; echo' <tr>'; echo' <td height="409"></td>'; echo' <td valign="top" bgcolor="#FFFFFF"><table width="726" height="516" border="0">'; echo' <tr>'; echo' <td width="1"> </td>'; echo' <td width="204" class="text"><span class="headerText">'.$name.'</span></td>'; echo' <td width="507"> </td>'; echo' </tr>'; echo' <tr>'; echo' <td height="210"> </td>'; echo' <td valign="top">'; if($photo == NULL) { echo '<div align="left"><img src ="images/noImage.jpg" alt="" width="200" height="200" align="middle"/></div>'; } else{ echo'<div align="left"><img src ="'.$photo.'" alt="" align="middle"/></div>'; } echo'</td>'; echo' <td valign="top"><table width="506" border="0" cellspacing="0">'; echo' <tr>'; echo' <td height="24" bgcolor="#437aa6"><span class="contentHeader"> Welcome!</span></td>'; echo' </tr>'; echo' <tr>'; echo' <td width="538" valign="top" bgcolor="#FAFAF5">'; } //displaying the words echo'<table width="480" border="0">'; echo'<tr>'; echo' <td height = "1"></td>'; echo" <td valign='top'><div align='justify'><span class='contentText'>Welcome to staffSignage's web portal.

wildteen88 Posted September 15, 2008 Share Posted September 15, 2008 You'll need to define the variables $photo, $name within your second while loop, otherwise the data used from the first loop will be used and thus you get the same results repeated over and over. chnage while ($row = mysql_fetch_array ($result)) { $staffid=$row['staffid']; if($photo == NULL) to while ($row = mysql_fetch_array ($result)) { $staffid = $row['staffid']; $photo = $row['photo']; $name = $row['name'] if($photo == NULL) As for why your images are not displaying change any instance of if($photo == NULL) to if(!empty($photo)) Quote Link to comment Share on other sites More sharing options...
