    <p>book.php</p> <pre><code>&lt;td&gt;&lt;input type="hidden" name="bus_fare" id="bus_fare" value="&lt;?php echo $row['price'];?&gt;"&gt; 1&lt;br&gt; &lt;input type="checkbox" name="seat[]" id="seat_1" value="1" onclick="seat_display(this.value);" /&gt;&lt;/td&gt; &lt;td&gt; &lt;input type="hidden" name="bus_fare" id="bus_fare" value=""&gt; 3&lt;br&gt; &lt;input type="checkbox" name="seat[]" id="seat_3" value="3" onclick="seat_display(this.value);" /&gt;&lt;/td&gt; &lt;td&gt; &lt;input type="hidden" name="bus_fare" id="bus_fare" value=""&gt; 5 &lt;br&gt; &lt;input type="checkbox" name="seat[]" id="seat_5" value="5" onclick="seat_display(this.value);" /&gt;&lt;/td&gt; &lt;input type="text" id="total_seats" name="total_seats" value="" readonly /&gt; </code></pre> <p>javascript</p> <pre><code>&lt;script type="text/javascript"&gt; var tot = 0; function seat_display(val) { seat_no = "seat_"+val; var s_no = document.getElementById(seat_no).value; var fare = parseInt(document.getElementById('bus_fare').value); if(document.getElementById(seat_no).checked) { document.getElementById('total_seats').value += s_no+","; tot=tot+fare; } else { tot=tot-fare; var arr = document.getElementById('total_seats').value; var seatno = arr.split(","); for( var i=0; i&lt;seatno.length; i++ ) { if(seatno[i] == s_no ) seatno.splice(i,1); } document.getElementById('total_seats').value = seatno; if(tot &lt; 0){ tot=0; } } document.getElementById('total_amt').value = tot; } &lt;/script&gt; </code></pre> <p>I want to disable those check boxes which are already checked and the values (checkbox) has already been sent to the database. Each checkbox has it's own unique value, so once an user check 1 or multiple checkbox in the book.php and the checkbox values are sent to the database, when next time another user comes he/she should see the already checked checkboxes are disabled, he/she cant select them. I want to use javascript for this. Any help?</p>

    1. COI dont understand why you are using the name bus_fare repeatedly. It will be having only the last value. All the previous values will be overridden. I think you can get values from database before building the form . If there is value already present disable it.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
