php results 2 table on page instead of one with all data - php

Question

I've made a script for a search mysql table, and instead of one table with more rows, he return me on results page one table for each person.
This is my results code by id from the search script. and returns table for each person
$id = $_GET['id'];
$sql = "select * from wp_certificari WHERE id = '{$id}'";
$rst = mysql_query($sql);
while($a_row = mysql_fetch_assoc($rst)) {
echo "<center>\n";
echo "<b>Detalii Certificat:</b>";
echo "<table border='1'>";
echo"<thead>";
echo "<th>Denumire certificare</th>";
echo "<th>Serie si numar certificare</th>";
echo "<th>Data certificarii</th>";
echo "<th>Valabilitate certificare</th>";
echo "<th>Sector Financiar</th></tr>";
echo"</thead>";
echo "<td class='lalign'>{$a_row['nume']}</td>" ;
echo "<td class='lalign'>{$a_row['serie_numar']}</td>" ;
echo "<td class='lalign'>{$a_row['data']}</td>" ;
echo "<td class='lalign'>{$a_row['valabilitate']}</td>" ;
echo "<td class='lalign'>{$a_row['sector_financiar']}</td></tr>" ;
echo"</table>";
echo "</center>\n";}

Answer 1

You need to write your table and table head html outside your while loop Add mysql_num_rows to check empty result and add mysql_real_escape_string to Escapes special characters in a string for use in an SQL statement
$id = $_GET['id'];
$id=mysql_real_escape_string($id);
$sql = "select * from wp_certificari WHERE id = '{$id}'";
$rst = mysql_query($sql);
$row=mysql_num_rows($rst);
if($row>0){
//outside while loop
echo "<center>\n";
echo "<b>Detalii Certificat:</b>";
echo "<table border='1'>";
echo"<thead>";
echo "<th>Denumire certificare</th>";
echo "<th>Serie si numar certificare</th>";
echo "<th>Data certificarii</th>";
echo "<th>Valabilitate certificare</th>";
echo "<th>Sector Financiar</th>";
echo"</thead>";
while($a_row = mysql_fetch_assoc($rst)) {
echo "<tr><td class='lalign'>{$a_row['nume']}</td>" ;
echo "<td class='lalign'>{$a_row['serie_numar']}</td>" ;
echo "<td class='lalign'>{$a_row['data']}</td>" ;
echo "<td class='lalign'>{$a_row['valabilitate']}</td>" ;
echo "<td class='lalign'>{$a_row['sector_financiar']}</td></tr>" ;
}
//outside while loop
echo"</table>";
echo "</center>\n";
}
Note:- Don't use mysql because it is deprecated instead use mysqli or
PDO

Answer 2

You have to get table part outside from while loop.
$id = $_GET['id'];
$sql = "select * from wp_certificari WHERE id = '{$id}'";
$rst = mysql_query($sql);
echo "<center>\n";
echo "<b>Detalii Certificat:</b>";
echo "<table border='1'>";
echo "<thead>";
echo "<tr>";
echo "<th>Denumire certificare</th>";
echo "<th>Serie si numar certificare</th>";
echo "<th>Data certificarii</th>";
echo "<th>Valabilitate certificare</th>";
echo "<th>Sector Financiar</th></tr>";
echo "</thead><tbody>";
while($a_row = mysql_fetch_assoc($rst)) {
echo "<tr>";
echo "<td class='lalign'>{$a_row['nume']}</td>" ;
echo "<td class='lalign'>{$a_row['serie_numar']}</td>" ;
echo "<td class='lalign'>{$a_row['data']}</td>" ;
echo "<td class='lalign'>{$a_row['valabilitate']}</td>" ;
echo "<td class='lalign'>{$a_row['sector_financiar']}</td></tr>";
}
echo"</tbody></table>";
echo "</center>\n";
