php - MySQL link to return results -


i have image displayed table , want user able click image directs them page returns rest of data row. need php loop this? can't quite figure out. returns last name, first name, , image:

    <?php     if (isset($_get['lastname'])) {     $ln = $_get['lastname'];     }         include 'connection.php';         $query = "select * residents lastname '$ln%' ";         $result = mysql_query($query);       while($person = mysql_fetch_array($result)) { ?>     <div class="media col-sm-4">          <a class="pull-left" href="redirectionpage.php?<?php echo $person['id'];?>.php">     <img class="media-object" src="upload/<?php echo $person['picture'];?>"   width="100" height="100"/>     </a>     <div class="media-body">      <h4 class="media-heading"><?php echo $person['lastname'] . ", " . $person['firstname']; ?></h4>     </div>     </div>     <?php }>?

is best way accomplish redirecting user new page , using mysql statement display new data?

this code other page:

    <?php     //gets data database         include ('header.php');         include ('footer.php');         include ('connection.php');            $query = "select * residents id = lastname limit 1";         $result = mysql_query($query);          while($row = mysql_fetch_array($result)){        $outputpicture.='<div><p><img src="upload/' . $row['picture'].'" width="450" height="550"/></p></div>';        $outputname.= $row['lastname'] . ", " . $row['firstname']. '<br />';        $outputspouse.= $row['spouse']. '<br />';        $outputrelatives.= $row['relatives']. '<br />';        $outputaddress.= $row['address']. '<br />';        $outputbirthday.= $row['birthday']. '<br />';        $outputbegan.= $row['beganresidence']. '<br />';        $outputended.= $row['endedresidence']. '<br />';        $outputformer.= $row['formerresidence']. '<br />';        $outputcareer.= $row['career']. '<br />';        $outputeducation.= $row['education']. '<br />';        $outputmaritalstatus.= $row['maritalstatus']. '<br />';        $outputsiblings.= $row['siblings']. '<br />';        $outputspecialinterests.= $row['specialinterests'].'<br />';        }         ?>

the link needs changed to

<a class="pull-left" href="redirectionpage.php?id=<?php echo $person['id'];?>">

adding id= allow access id parameter in redirectionpage.php via $_get superglobal.

$id = $_get['id'];

you can use $id variable select specified row database. see lot of examples this:

$query = "select * residents id = $id";

this works should not it, because creates sql injection vulnerability. read prepared statements , create sql can pass id paramater.

$stmt = $pdo->prepare("select * residents id = :id"); $stmt->bindvalue(':id', $id, pdo::param_int); $stmt->execute();

this should applied code use select list of images.

assuming id key residents table, should select 1 record, not need while loop. can use 1 fetch.
