I want to display array values followed by a checkbox inside a html table using a for loop :
<?php
for ($j = 0; $j < $data['user']['droit']['cnt']; $j++)
{
?>
<table>
<tr>
<td><?php echo $data['user']['droit'][$j]['menu_titre']; ?></td>
<?php
$checked = "";
if (is_array($data['user_droit']) && count($data['user_droit']) > 0 && in_array($data['user']['droit'][$j]['menu_code'], $data['user_droit']))
$checked = " checked ";
?>
<td><input type="checkbox" name="<?php echo $data['user']['droit'][$j]['menu_code']; ?>"
value="<?php echo $data['user']['droit'][$j]['menu_code']; ?>" <?php echo $checked ?> />
</td>
</tr>
</table>
<?php
}
?>
I don't know how to make the individual checkbox to be disabled if it is checked from the loop. How to achieve that ?
or set $checked = " checked disabled ";
<?php
for ($j = 0; $j < $data['user']['droit']['cnt']; $j++)
{
?>
<table>
<tr>
<td><?php echo $data['user']['droit'][$j]['menu_titre']; ?></td>
<?php
$checked = "";
if (is_array($data['user_droit']) && count($data['user_droit']) > 0 && in_array($data['user']['droit'][$j]['menu_code'], $data['user_droit']))
{
$checked = " checked disabled ";
}
?>
<td><input type="checkbox" name="<?php echo $data['user']['droit'][$j]['menu_code']; ?>"
value="<?php echo $data['user']['droit'][$j]['menu_code']; ?>" <?php echo $checked ?> />
</td>
</tr>
</table>
<?php
}
?>

i have this form
how do i update this record by row with checkbox ? the checkbox hold a value i sent from previous form .
this would be the database
is this right??
while ($row = mysqli_fetch_array($result)){
.
.
.
.
<td><center>
<input type="hidden" name="matric[]" value="<?php echo $matric?>"/><p>
<input class="w3-check" type="checkbox" value='$hour' name="unattend<?php echo $matric?>[]">
<label> Unattend</label></p> </center></td>
<td><center>
<input type="hidden" name="matric[]" value="<?php echo $matric?>"/><p>
<input class="w3-check" type="checkbox" value='$hour' name="mc<?php echo $matric?>[]">
<label> I have MC </label></p> </center></td> }
how would the update mysql be ?
This is the form
<?php
$i = 1;
while ($row = mysqli_fetch_array($result)) {
$id=$row['matric_number'];
?>
<form method="POST" action="attend.php">
<tr>
<td><center><?php echo $i; ?></center></td>
<td><center><?php echo $row['student_name']; ?></center></td>
<td><center><?php echo $row['matric_number']; ?></center></td>
<td><center>
<p>
<input class="w3-check" name="unattend[]" type="checkbox" id="unattend[]" value="<?php echo $id; ?>">
<label> Unattend</label></p> </center></td>
<td><center>
<p>
<input class="w3-check" name="mc[]" type="checkbox" id="mc[]" value="<?php echo $id; ?>">
<label> I have MC </label></p> </center></td>
<td><center>
<?php echo "<a href=student.php?id1=".$row['matric_number'].">"."Details"; ?></center></td>
</tr>
<?php
$i++;
}
mysqli_close ($link);
?>
</table>
The php to update the data by row is
<?php
if (isset($_POST['unattend'])) {
$hour=$_POST['hour'];
$id=$_POST['unattend'];
$N = count($id);
for($i=0; $i < $N; $i++)
{
$select = mysqli_query($link,"SELECT * FROM pbu WHERE matric_number='$id[$i]'")or die(mysql_error());
while ($row = mysqli_fetch_array($select)) {
$value=$row['unattend'];
$total=$value+$hour;
$result = mysqli_query($link,"UPDATE pbu SET unattend='$total' WHERE matric_number='$id[$i]'")or die(mysql_error());
echo "unattend is updated for matric number ".$id[$i]."<br>";
}
}
}
if (isset($_POST['mc'])){
$id1=$_POST['mc'];
$N = count($id1);
for($i=0; $i < $N; $i++)
{
$select = mysqli_query($link,"SELECT * FROM pbu WHERE matric_number='$id[$i]'")or die(mysql_error());
while ($row = mysqli_fetch_array($select)) {
$values=$row['mc'];
$totals=$values+$hour;
$results = mysqli_query($link,"UPDATE pbu SET mc='$totals' WHERE matric_number='$id1[$i]'")or die(mysql_error());
echo "mc is updated for ".$id1[$i]."<br>";
}
}
}
else{
echo "nothing inserted";
}
?>

So the code selects the survey from the survey table and then gets all the questions from survey_questions for the selected survey.
Each question has up to 8 answers (all checkboxes with value of Y)
The user goes though and checks the box for the answer(s) they choose so when the form is submitted, how can i make it insert into surveys_completed table each answer.
So for each question, it adds a row in the surveys_completed table.
The structure of the surveys_completed table is:
sequence
survey_sequence
question_seq
answer1
answer2
answer3
answer4
answer5
answer6
answer7
answer8
create a page called getval.php then put the below code and you have to make sure you
connect to the database using pdo thats when this code is gonna work for you .
H i hope it will help you good luck
<?php
$answer1=(isset($_POST['answer1']))? trim($_POST['answer1']): '';
$answer2=(isset($_POST['answer2']))? trim($_POST['answer2']): '';

You can use the checked attribute.
<input type="radio" checked>
So if you had some variables (booleans), $opt1, $opt2, $opt3, $opt4, then you could do something similar to this:
<input type="radio" name="opt1" <?php if ($opt1) echo "checked"; ?> />
<input type="radio" name="opt2" <?php if ($opt2) echo "checked"; ?> />
<input type="radio" name="opt3" <?php if ($opt3) echo "checked"; ?> />
<input type="radio" name="opt4" <?php if ($opt4) echo "checked"; ?> />
I have the following code:
<form action="" method="POST">
<?php
$count = isset($_POST['count']) ? $_POST['count'] : 1;
if($count > 11) $count = 11;
?>
<table>
<!-- Keeps track of the current number of rows -->
<input type="hidden" name="count" value="<?php echo $count+1; ?>"/>
<?php for($i = 0; $i < $count; $i++):
// Loop through all rows gathering the data here, and then creating the fields below
$val0 = isset($_POST['field'][$i]['0']) ? $_POST['field'][$i]['0'] : '';
$val1 = isset($_POST['field'][$i]['1']) ? $_POST['field'][$i]['1'] : '';
$val2 = isset($_POST['field'][$i]['2']) ? $_POST['field'][$i]['2'] : '';
?>
<tr>
<td><input name="field[<?php echo $i; ?>][0]" value="<?php echo $val0; ?>"/></td>
<td><input name="field[<?php echo $i; ?>][1]" value="<?php echo $val1; ?>"/></td>
<td><input name="field[<?php echo $i; ?>][2]" value="<?php echo $val2; ?>"/></td>

<?php endfor; ?>

How can I make the fields into a dropdowns and when you press submit echo out the dropdown as text instead as a dropdown?
First: Fill in the following:
Make this to action="mytestpage.php"
Give this a name attribue like: name="send"
Give these fields types like: type="Text"
If you want a dropdown menu use <select> in combination with <option>...
Here is a start to learn how:
http://www.echoecho.com/htmlforms11.htm
To print your result do this:
if(isset($_POST['send'])
{
print($_POST['youroptionname']);
}
I hope it helped you.

The problem is when I press submit it add 3 other fields but it clears the other fields. How can I keep the content from the fields but make them uneditable?
You are not echoing your values and your $count should be $i, as you'll end up with same field names
<form action="" method="POST">

$count = isset($_POST['count']) ? $_POST['count'] : 1;
if($count > 11) $count = 11;
