I'm trying make a form where me or user can insert data. Some parts are coming form data base like: Work name and work price. In input fields can insert work amount. In each input row have checkbox, if checkbox ar checked, that row will be seen in php.
<table class="table">
<thead>
<tr>
<th scope="col">*</th>
<th scope="col">Work name</th>
<th scope="col">Quantity</th>
<th scope="col">Price for unit</th>
<th scope="col">Total price</th>
</tr>
</thead>
<form method="POST" action="process/pdf.process.php">
<tbody>
<?php
$works = ORM::for_table('work')->find_many();
foreach($works as $work){
?>
<tr id="<?php echo $work->id; ?>">
<td><input type="checkbox" name="useit[]" value="<?php echo $work->id; ?>"/></td>
<td><?php echo $work->name; ?></td>
<td><input type="text" placeholder="" class="amount"/> <?php echo $work->unit; ?></td>
<td class="work_price" data="<?php echo $work->price; ?>"><?php echo $work->price.'€/'.$work->unit; ?></td>
<td class="total_price">0€</td>
<input type="" name="work_id[]" value="<?php echo $work->id; ?>" />
<input type="hidden" name="work_name[]" value="<?php echo $work->name; ?>" />
<input type="hidden" name="amount[]" class="<?php echo $work->id; ?>_copy_amount" value="" />
<input type="hidden" name="unit[]" value="<?php echo $work->unit; ?>" />
<input type="hidden" name="unit_price[]" value="<?php echo $work->price; ?>€" />
<input type="hidden" name="unit_total[]" class="<?php echo $work->id; ?>_copy_total" value="" />
</tr>
<?php
}
?>
</tbody>
<input type="submit" name="do_pdf" value="Pga jkāuztaisa ar jquery" />
</form>
</table>
Now, there is php, but how can i show only checked rows in while loop?
<?php
$data = array();
$work_id = array();
$work_names = $_POST['work_name'];
$amounts = $_POST['amount'];
$units = $_POST['unit'];
$units_prices = $_POST['unit_price'];
$units_total = $_POST['unit_total'];
if(isset($_POST['useit'])){
$work_id = $_POST['useit'];
}
$data = array($work_id, $work_names, $amounts, $units, $units_prices, $units_total);
echo '<pre>';
echo htmlspecialchars(print_r($data, true));
echo '</pre>';
?>
There are different possibilities how to do that. One Suggestion (i limit it to the parts which are relevant)
form (note that i gave work_name the id as an index, use_it not (but it could have)
<td><input type="checkbox" name="useit[]" value="<?php echo $work->id; ?>"/></td>
<input type="hidden" name="work_name[<?php echo $work->id?>]" value="<?php echo $work->name; ?>" />
The form only submits the checked checkboxes values in an array, all other are omited. Therefore we could loop over the checked checkbox values like this
foreach($_POST['useit'] as $work_id){
$work_name = $work_names[$work_id];
//do something with the checked rows only (all others are not looped over)
}
This is only possible, due to the given id as an array key in the form work_name[<?php echo $work->id?>].
A general sidenote for better (and more secure) code: please note that your data could be modified by the user, and send back with wrong data (or worse). So please make sure to sanitize your input, or probably better in this case only submit the id in question and the new data and pickup the rest directly from your database. So you can make sure the hidden data has not been modified on the client side and send back wrong.
I am try to inset multiple rows to new table fetched from other table, but problem is that only last single row is being inserted and no other now is getting insert, so please tell the issue where i am lacking

You need to have unique name for each fields. What you can do is have a counter in loop and add it the names of the fields to make it unique.
Sample:
$ctr = 0;
while($r=mysql_fetch_array($val)){
echo "<input type="text" name='teacher_".$ctr."'>";
$ctr++;
}
Or make the names array, and loop through the values in saving the data.
while($r=mysql_fetch_array($val)){
echo "<input type="text" name='teacher[]'>";
}
I think you should study PHP a bit more... As i can see in your code, you haven't understood fundamentals of PHP.
1: Normally, you won't mix up HTML and PHP like you did in your first code. Its just confusing and really annoying to read the code later.
2: When you post your form, for example the variable $_POST['student_name']; will just contain the value of the last row (your problem). So, why? Because you can't assign more than one value to a variable. Or at least, not the way you tried it. Array would be a good keywoard for this problem.
3: Please check your SQL syntax... Thats why i'm saying you haven't understand fundamentals... http://www.w3schools.com/sql/sql_insert.asp
Why you're repeating your values? You think the second time the variables will contain the values of the next row? Thats just false. A Variable contains everytime the same value, as long as you don't assign a new value to it.
4: mysql is depracted. Use mysqli or PDO instead.
My tip: You need to have unique input names. Just take a look at PHP, how for/while loops work, study a bit more and try it again. It's not difficult to solve, but i think you'll learn a lot more if we don't give you the direct solution.
Now mysql is depracted. So, you can use mysqli or PDO instead.
I can use now PDO. Please follow bellow code carefully:
<?php
$user = 'root';
$pass = '';
$dbh = new PDO('mysql:host=localhost;dbname=education', $user, $pass);
try {
$select = $dbh->query('SELECT * from student');
} catch (PDOException $e) {
print "Error!: " . $e->getMessage() . "<br/>";
die();
}
?>

<body>
<form action="submit.php" method="post" >

<tr>
<th>Teacher name</th>
<th>Date</th>
<th>Roll No</th>
<th>Student name</th>
<th>Father name</th>

<th>Status(L)</th>
</tr>
<?php
foreach($select as $val) {
?>
<tr style="border:2px solid black;">
<td><input type="text" name="teacher" value="<?php echo $s; ?>"></td>
<td><input type="text" name="date" value="<?php echo $date; ?>"></td>
<td><input name="roll_no" value="<?php echo $r['roll_no']; ?>"></td>
<td><input name="student_name" value="<?php echo $r['student_name'] ?>"></td>
<td><input name="father_name" value="<?php echo $r['father_name'] ?>"></td>
<td><input name="addhaar_no" value="<?php echo $r['addhaar_no'] ?>"></td>
<td><input type="checkbox" value="present" name="status"> Present</td>
<td><input type="checkbox" name="status" value="absent">Absent</td>
<td><input type="checkbox" name="status" value="leave">Leave</td>
</tr>
<?php
}
?>
</table>
<input type="submit" name="submit" value="submit">
</form>
</body>
</html>
For submit.php code bellow
<?php
$user = 'root';
$pass = '';
$dbh = new PDO('mysql:host=localhost;dbname=education', $user, $pass);
$stmt = $dbh->prepare("INSERT INTO attandance (roll_no, student_name, father_name, addhaar_no, status) VALUES (?, ?, ?, ?, ?)");
$stmt->bindParam(1, $roll_no);
$stmt->bindParam(2, $student_name);
$stmt->bindParam(2, $father_name);
$stmt->bindParam(2, $addhaar_no);
$stmt->bindParam(2, $status);
//if you insert 2 time then
for($x=0; $x<2; $x++) {
$roll_no = $_POST['roll_no'];
$student_name = $_POST['student_name'];
$father_name = $_POST['father_name'];
$addhaar_no = $_POST['addhaar_no'];
$status = $_POST['status'];
$stmt->execute();
}
?>
my problem goes like this:
my home page has tables with rows pulled from the database (while loops)
each row has a - cell in which he can add an event to that specific row
in order to do that i send the row id as a $_GET variable from the home page table
and in the "add event" page i store it as a variable
but when i submit my addevent form without filling it properly (as i coded) it simply refreshes the form only without the row id in the url therefor also the query i do in the beginning of the page for pulling the row data can no longer execute and that pops a PHP error
for the id variable which i sign it the $_GET and the query (mysql fetch array).
also of course all the data which i display in the form from that query is gone.
any suggestions on how to approach this ? thanks in advance, Regards.
EDIT:** kill the new guy! -Sorry i guess
home page where i send the id :
$sql = "SELECT * FROM alarms WHERE alarmstatus = 'OFF' and starttime='::' ORDER BY clientid ASC";
$query = mysql_query($sql);
echo "<table cellpadding='1px' border='1px' bordercolor='#0066FF' cellspacing='0'>
<form action='hpage.php' method='get'>";
while($fetch = mysql_fetch_array($query)) {
echo "<tr>
<td>
".$fetch['clientid']."</td>
<td>".$fetch['controller']."</td>
<td>".$fetch['typeid']."</td>
<td style='color: red'>".$fetch['alarmstatus']."</td>
<td>".$fetch['starttime']."</td>
<td>".$fetch['endtime']."</td>
<td><a href='includes/editalarm.php?id=".$fetch['id']."'>Edit</a></td>
<td><a href='includes/addevent.php?id=".$fetch['id']."'>Add event</a></td>
<td><a href='includes/deletealarm.php?id=".$fetch['id']."'>Delete</a></td>
</tr>";
}
the add event where i get the variable and make the query:
$alarmid = $_GET['id'];
$sql = "SELECT * FROM alarms WHERE id=".$alarmid;
$query = mysql_query($sql);
$fetch = mysql_fetch_array($query);
?>
the form:
<table cellpadding="2px" cellspacing="0" >

Your form action is POST. If you change that to GET then you will have the form as $_GET.
I've a doubt. I've 3 textboxes and each is having checkboxes next to it. I want to display
the values of only those textboxes whose respective checkboxes are clicked. Following is the attached HTML and PHP codes:
<html>
<head>
</head>
<body>
<form name="f" method="post" action="4.php">
<table>
<tr>
<th> Facility </th>
</tr>
<tr>
<td><input type="text" name="a1" value="a"></td><td><input type="checkbox" id="facility[]" name="facility[]" value="Hostel"></td>
</tr>
<tr>
<td><input type="text" name="b1" value="b"></td><td><input type="checkbox" id="facility[]" name="facility[]" value="Transport"></td>
</tr>
<tr>
<td><input type="text" name="c1" value="c"></td><td><input type="checkbox" id="facility[]" name="facility[]" value="Food"></td>
</tr>
<tr>
<td colspan="3"><input type="submit" value="submit" /></td>
</tr>
</table>
</form>
</body>
</html>
and below is the PHP part.
<?php
$a=$_POST['a1'];
$b=$_POST['b1'];
$c=$_POST['c1'];
$facilityArray = $_POST['facility'];
$facility = "";
if(count($facilityArray) > 0)
{
foreach($facilityArray as $fac)
{
$facility .= " " . $fac;
}
}
echo $facility; echo "<br>";
echo $a; echo "<br>";
echo $b; echo "<br>";
echo $c;
?>
With the help of following codes I am able to display all the values of checked checkboxes. I am also able to display the values of all the textboxes. But I actually want to display the values of only those textboxes whose respective checkboxes are clicked. I know it may be a very basic question but please help me grow in PHP. Thanks in advance... :(
Your textboxes should also be in an array post to achieve this.
To achieve this change the input lines as:
<td><input type="text" name="textboxes[]" value="a"></td><td><input type="checkbox" id="facility[]" name="facility[]"></td>
From php you'll be getting the posted textboxes in an array as:
$textbox=$_POST['textboxes'];
You should then loop through the checkboxes array and if the corresponding checkbox is "on" (clicked), then display the textboxes value. To do this you would also need a counter to make sure you are on the same array index for both checkboxes and textboxes:
if(count($facilityArray) > 0)
{
$i = 0;
foreach($facilityArray as $fac)
{
if($fac == "on")
{
echo $textbox[$i] . "</br>";
}
$i ++;
}
}
I've also added a name to your submit button so you only check the form when it is submitted.
Your page should now look something like this:
<?php
if(isset($_POST['submit']))
{
$textbox=$_POST['textboxes'];
$facilityArray = $_POST['facility'];
if(count($facilityArray) > 0)
{
$i = 0;
foreach($facilityArray as $fac)
{
if($fac == "on")
{
echo $textbox[$i] . "</br>";
}
$i ++;
}
}
}
?>
<form name="f" method="post" action="4.php">
<table>
<tr>
<th> Facility </th>
</tr>
<tr>
<td><input type="text" name="textboxes[]" value="a"></td><td><input type="checkbox" id="facility[]" name="facility[]"></td>
</tr>
<tr>
<td><input type="text" name="textboxes[]" value="b"></td><td><input type="checkbox" id="facility[]" name="facility[]"></td>
</tr>
<tr>
<td><input type="text" name="textboxes[]" value="c"></td><td><input type="checkbox" id="facility[]" name="facility[]"></td>
</tr>
<tr>
<td colspan="3"><input name="submit" type="submit" value="submit" /></td>
</tr>
</table>
</form>
UPDATE:
To make sure that the $_POST variable exists before assigning it to a variable we use the isset(). In your case just update the php segment as:
<?php
if(isset($_POST['submit']))
{
if(isset($_POST['textboxes']))
{
$textbox=$_POST['textboxes'];
if(isset($_POST['facility']))
{
$facilityArray = $_POST['facility'];
if(count($facilityArray) > 0)
{
$i = 0;
foreach($facilityArray as $fac)
{
if($fac == "on")
{
echo $textbox[$i] . "</br>";
}
$i ++;
}
}
}
}
}
?>
Where the only changes are the addition of another two if statements that take a boolean flag from the isset() function according to whether the $_POST variable has been posted successfully
if(isset($_POST['textboxes']))
AND
if(isset($_POST['facility']))
I want to let the user select one "row" to use to submit the with to request a report type. How can I put radio buttons in the first column of a table and whichever is selected is the active row that gets sent to the next page via the submit button?
I think Andreas is on the right track, but it's not as useful as it could be. This should be a bit better:
<?php
blah ...
echo <<<HTML
<form action="handler.php" action="post">
<table>
HTML;
foreach ($rows as $row)
{
$id = $row['id'];
$text = $row['text']; // escape this unless you know it's safe
echo <<<HTML
<tr>
<td><input type="radio" value="$id" name="theRadioButton" /></td>
<td><input type="text" name="textfield_$id" value="$text" /></td>
</tr>
HTML;
}
echo <<<HTML
</table>
</form>
HTML;
form handler:
<?php
$id = isset($_POST['theRadioButton']) ? $_POST['theRadioButton'] : null;
if ($id)
{
$textfield = $_POST["textfield_$id"];
}
?>
If you want to do it in pure PHP, i guess you could do this:
<form action="ascript.php" action="post">
<table>
<tr>
<td><input type="radio" value="row1" name="theRadioButton" /></td>
<td><input type="text" name="row1textfield" /></td>
</tr>
<tr>
<td><input type="radio" value="row2" name="theRadioButton" /></td>
<td><input type="text" name="row2textfield" /></td>
</tr>
<tr>
<td><input type="radio" value="row3" name="theRadioButton" /></td>
<td><input type="text" name="row3textfield" /></td>
</tr>
</table>
</form>
ascript.php
<?php
if ($_POST['theRadioButton'] == "row1") {
echo $_POST['row1textfield'];
// Handle row 1 ..
}
else if ($_POST['theRadioButton'] == "row2") {
echo $_POST['row2textfield'];
// Handle row 2 ..
}
else if ($_POST['theRadioButton'] == "row3") {
echo $_POST['row3textfield'];
// Handle row 3 ..
}
?>
However, if you're willing to use some jQuery, you could just name the textfields the same thing and disable the fields you're not going to use. Here's a fiddle: http://jsfiddle.net/rrvQu/1/
