make checkbox automatically checked within table PHP - php

Question

I am new to PHP and I have problem. I have a table with check boxes. I need to add if statement inside the check box.
echo "<div class='table1'>
<table>
<tr>
<td></td>
<td>Module code</td>
<td>Module Title</td>
<td>Option</td>
</tr>";
echo "<form action='confirmsubmission.php' method='post'>";
while($row = mysql_fetch_array($result))
{
echo "<tr>";
echo "<td>" . "<input type='checkbox' name='check[]'
value='".$row['module_id']."' />" . "</td>";
echo "<td>" . $row['module_id'] . "</td>";
echo "<td>" . $row['module_title'] . "<a href=# content='".$row['description']."'
class='tooltip'><span title='Module Description'><img src='images/i.png'/></span>
</a>". "</td>";
echo "<td>" . $row['module_choice'] . "</td>";
echo "</tr>";
}
echo "</table></div>";
Below is a If statement I need to add after value='".$row['module_id']."'
if($row['module_choice']=='Mandatory'){ echo "checked=\"true\""; }

Answer 1

A bit of a mouthful, but try:
...
echo "<td>" . "<input type='checkbox' name='check[]' value='".$row['module_id']."'".($row['module_choice']=='Mandatory' ? 'checked="true"' : "")." />" . "</td>";
...

Even though I'll advise you to use a templating system (Smarty, etc.), you can do the following code:
echo "<div class='table1'>
<form action='confirmsubmission.php' method='post'>
<table>
<tr>
<td></td>
<td>Module code</td>
<td>Module Title</td>
<td>Option</td>
</tr>";
while($row = mysql_fetch_array($result))
{
echo "<tr>";
echo "<td>" . "<input type='checkbox' name='check[]'
value='".$row['module_id']."'";
if($row['module_choice']=='Mandatory'){
echo " checked='checked' ";
}
echo "/>" . "</td>";
echo "<td>" . $row['module_id'] . "</td>";
echo "<td>" . $row['module_title'] . "<a href=# content='".$row['description']."'
class='tooltip'><span title='Module Description'><img src='images/i.png'/></span>
</a>". "</td>";
echo "<td>" . $row['module_choice'] . "</td>";
echo "</tr>";
}
echo "</table></form></div>";
