php add html element inside while loop - php

Question

Hello here is my code :
<table class="table table-hover table-bordered">
<tr>
<th class="well" style="text-align:center">ID</th>
<th class="well" style="text-align:center">Email</th>
<th class="well" style="text-align:center">User level</th>
</tr>';
<?
$code_sql = "SELECT user_id, user_email,user_level FROM users ORDER BY user_id ASC ";
$code_query = mysql_query($code_sql) or die(error_sql(mysql_error(),__LINE__,__FILE__));
$sql_rows = mysql_num_rows($code_query);
if($sql_rows > 0){
while($rows = mysql_fetch_object($code_query)){
$user_id = intval($rows->user_id);
$user_level= intval($rows->user_level);
$user_email = htmlspecialchars($rows->user_email);
echo ' <tr>
<td>'.$user_id.'</td>
<td>'.$user_email.'</td>
<td>'.$user_level.'</td>
</tr>';
}
mysql_free_result($code_query);
}else{
echo '<tr>
<td>
<font color="red">no data found</font>
</td>
</tr>';
}
echo '</table>';
?>
the output of the code will be like .
<table class="table table-hover table-bordered">
<tr>
<th class="well" style="text-align:center">ID</th>
<th class="well" style="text-align:center">Email</th>
<th class="well" style="text-align:center">User level</th>
</tr>
<tr>
<td>1</td>
<td>test1#gmail.com</td>
<td>1</td>
</tr>
<tr>
<td>2</td>
<td>test2#gmail.com</td>
<td>2</td>
</tr>
<tr>
<td>3</td>
<td>test3#gmail.com</td>
<td>2</td>
</tr>
<tr>
<td>4</td>
<td>test4#gmail.com</td>
<td>1</td>
</tr>
</table>
(1 = normal user , and 2 = admin for user level) but what I want is something .like that
<table class="table table-hover table-bordered">
<tr>
<th class="well" style="text-align:center">ID</th>
<th class="well" style="text-align:center">Email</th>
<th class="well" style="text-align:center">User level</th>
</tr>
<div id="users">
<tr>
<td>1</td>
<td>test1#gmail.com</td>
<td>1</td>
</tr>
<tr>
<td>4</td>
<td>test4#gmail.com</td>
<td>1</td>
</tr>
</div>
<div id="admins">
<tr>
<td>2</td>
<td>test2#gmail.com</td>
<td>2</td>
</tr>
<tr>
<td>3</td>
<td>test3#gmail.com</td>
<td>2</td>
</tr>
</div>
</table>
I want to add a div id="users" that will contain all users from database that have user_level = 1 and another div id="admins" for user_level = 2.

Answer 1

try the following code, you need to create div's based on conditions like if the iteration number 1 then insert div(open) before content and after content(close)...and the if iteration number is 3 then again insert the div(open) before content an after content(close)
<table class="table table-hover table-bordered">
<tr>
<th class="well" style="text-align:center">ID</th>
<th class="well" style="text-align:center">Email</th>
<th class="well" style="text-align:center">User level</th>
</tr>
<?php
$code_sql = "SELECT user_id, user_email,user_level FROM users ORDER BY user_id ASC ";
$code_query = mysql_query($code_sql) or die(error_sql(mysql_error(),__LINE__,__FILE__));
$sql_rows = mysql_num_rows($code_query);
if($sql_rows > 0){
$i=0;
while($rows = mysql_fetch_object($code_query)){
$user_id = intval($rows->user_id);
$user_level= intval($rows->user_level);
$user_email = htmlspecialchars($rows->user_email);
if($i==0){?><div id='users'><?php }elseif($i==2){?><div id='admins'><?php }
echo ' <tr>
<td>'.$user_id.'</td>
<td>'.$user_email.'</td>
<td>'.$user_level.'</td>
</tr>';
if($i==0){?></div><?php }elseif($i==2){?></div><?php }
$i++;
}
mysql_free_result($code_query);
}else{
echo '<tr>
<td>
<font color="red">no data found</font>
</td>
</tr>';
}
echo '</table>';
?>

Try the below code with tbody to group table rows,
<?php
$code_sql = "SELECT user_id, user_email,user_level FROM users ORDER BY user_level ASC, user_id ASC ";
$code_query = mysql_query($code_sql) or die(error_sql(mysql_error(),__LINE__,__FILE__));
$sql_rows = mysql_num_rows($code_query);
if($sql_rows > 0){
$newgroup = false;
$groupid = array(1=>'users', 2=>'admins');
while($rows = mysql_fetch_object($code_query)){
$user_id = intval($rows->user_id);
$user_level= intval($rows->user_level);
$user_email = htmlspecialchars($rows->user_email);
if($newgroup != $user_level) {
if($newgroup != false) echo '</tbody>';
echo '<tbody id="'.$groupid[$user_level].'">';
$newgroup = $user_level;
}
echo ' <tr>
<td>'.$user_id.'</td>
<td>'.$user_email.'</td>
<td>'.$user_level.'</td>
</tr>';
}
echo '</tbody>';
mysql_free_result($code_query);
}else{
echo '<tr>
<td>
<font color="red">no data found</font>
</td>
</tr>';
}
echo '</table>';
?>
Note:
It would work if you just want to group table rows. But if you want to add additional features like animation then you might need to add more css/jQuery.
Additional suggestions:
1. You should start using mysqli or PDO
2. You should start using css to replace font tags.
