I'm trying to make a school attendance tracker with codeigniter. I don't know how to get both the Student_no AND the radio button value Present or Absent to enter into the database. The values of student_no and the radio buttons are both being posted as NULL to my controller?
My Controller file
function insertAttendance(){
$student_no=$this->input->post('student_no');
$attendance=$this->input->post('attendance');
$data = array(
'student_no'=>$student_no,
'attendance'=>$attendance
);
//$this->form_validation->set_data($data);
$this->db->set($data);
$this->db->insert('attendance',$data);
}
My view
<h3>ATTENDANCE TRACKER</h3>
<table class="table table-lg" name="student_no">
<tr>
<th>Student_NO</th>
<th>Student name</th>
<th>Student DOB</th>
<th>Attendance</th>
</tr>
<?php foreach ($query->result_array() as $row): {?>
<tr>
<td><?php echo $row['student_no'];?></td>
<td><?php echo $row['student_name'];?></td>
<td><?php echo $row['student_dob'];?></td>
<tr>
<label>
<label><input type="radio" name="attendance[<?php echo $row['player_id']; ?>]" value="Yes">Present</label>
<label><input type="radio" name="attendance[<?php echo $row['player_id']; ?>]" value="No">Absent</label>
</td> </tr>
<?php } ?>
<?php endforeach; ?>
</tr>
</tbody>
</table>
Where is the form field for student_no? I don't see it, it should throw an undefined notice.
Assuming $row['player_id'] is not empty, $this->input->post('attendance') will not exist.
<input type="radio" name="attendance_<?php echo $row['player_id']; ?>" value="Yes">
Maybe try like this and create a form field for student_no (hidden field?).
You do not need
$this->db->set($data);
as you are already passing the $data array in the insert part of the builder.
EDIT:
I updated the input field code. Put the form tags inside the foreach statement so that each student has its own form.
Each form needs a hidden field to pass along the player_id.
<input type="hidden" name="player_id" value="<?php echo $row['player_id']; ?>">
In the controller, validate POST data and use the player_id you passed through:
$this->input->post('attendance_'. $this->input->post('player_id'))
or similar
EDIT 2:
You can also put the <form> tags outside the foreach statement but then we need to loop through all the POST data in the controller. This allows you to have one submit button on the whole form but does make your backend work more complex.

I am trying to make a rating system using multi-select dynamically generated from rating text on the database. The final result should look like this: Rating Service but now I need to save selected option after save is clicked.
in the database there is two table the first one have 2 column the first is the id and the second is the text of the rate
the second table is where i wont to save the selection that the user chose using php
page code
<table class="table table-striped">
<thead>
<tr>
<th>#</th>
<th>About</th>
<th>Provider</th>
<th>Rating</th>
</tr>
</thead>
<?php
$query_rate_text = "SELECT * FROM rateing_text";
$selecting_rates = mysqli_query($con,$query_rate_text);
$i = 0;
while($row_rate = mysqli_fetch_assoc($selecting_rates)){
$rate_id= $row_rate['rate_id'];
$rate_text= $row_rate['rate_text'];
$i++
?>
<form name="rating_form">
<tbody>
<tr>
<td><?php echo $i ?></td>
<td> <?php echo $rate_text ?></td>
<td><span class="badge badge-danger">
<?php echo $provider_name ?></span></td>
<td>
<select name="p<?php echo $i ?>">
<option value="1">Very Bad</option>
<option value="2">Bad</option>
<option value="3">Good</option>
<option value="4">Very Good</option>

</tr>
</tbody>
<?php } ?>
<tfoot>
<tr>
<td colspan="3"><button type="submit" name="save_rate"> Save </button> </td>
</tr>
</tfoot>
`enter code here`
</form>
</table>
How can I get info form the select and save them to the database ?
Radio button is much better than <select>.
The rate id and selected value must be passed as a key=>value
You need to stop using Word Press syntax.
Learn to use Herdoc Syntax
Using SELECT * is a poor standard practice.
Fetch array and assign values with a list
This code is untested.
<?php
echo <<<EOT
<form name="rating_form" action="#">
<table class="table table-striped">
<tr><th>#</th><th>About</th><th>Provider</th><th>Rating</th></tr>
EOT;
$query_rate_text = "SELECT `rate_id`,`rate_text` FROM rateing_text WHERE 1 ORDER BY `rate_id`";
$selecting_rates = mysqli_query($con,$query_rate_text);
$i = 0;
while(list($rate_id, $rate_text) = mysqli_fetch_array($selecting_rates)){
$i++;
echo "<tr><td>$i</td><td>$rate_text</td><td>$provider_name</td><td>5<input type="radio" name=\"$rate_id\" value=\"5\" /> 4<input type="radio" name=\"$rate_id\" value=\"4\" /> 3<input type="radio" name=\"$rate_id\" value=\"3\" /> 2<input type="radio" name=\"$rate_id\" value=\"2\" /> 1<input type="radio" name=\"$rate_id\" value=\"1\" /></td></tr>\n";
}
echo '</table><button type="submit" name="save_rate"> Save </button></form>';
?>
UPDATE
thank you very much that's helped to understand new way's,one more
thing how can i get the data out from this radio 5 buttons to insert
them to the database to the table named rating which have let's say 3
column id and provider name and the rate it self , again thank you for
helping
The radio input type is a more user friendly way then the cumbersome select.
The way I setup the radio buttons with the rate_id as the "name" so the selected "value" is passed as a key=>value pair to the form's action script.
Your select name should also contain the rate_id
The problem your code has is, the action script will receive will receive keys of sequential numbers that have no meaning and difficult to know how many were posted by the form.
To pass the provide name add a hidden input type:
<input type="hidden" name="provider" value="$provider_name" />
And I would remove the provider from the table td.
Not knowing your rate_id convention I could not improve the radio button naming convention.
The way I would do it is when passing key=>value pairs I would begin the key "name" with a unique character where no other "name" in the form would start with that character.
For example if the rate_id is a numeric value I may prepend a 'k' to the numeric key value.
So instead of
name=\"$rate_id\"
I would use
name=\"k$rate_id\"
The in the receiving action script I would get the key=>values like this
$provider_name = $_GET['provider']
foreach($_GET as $key => $value)){
if(substr($key,0,1) == 'k'){
$rate_id = intval(substr($key,1));
$rating = intval($value);
$sql = "INSERT INTO `table` (`rate_id`, `provider_name`, `rating`) VALUES ($rate_id, '$provider_name', $rating)";
mysqli_query($link,$sql);
}
}
I am actually starting my newest codes with HTML/PHP .
I am searching for retrieving data (list of persons) from mysql Data Base, displaying it into html table, then when I will clik on button "edit" it will show me in another page the details of the selected person like this :
It works fine for all the rows expects the firt row of the table.
Any help please !!!
there is my code :
<table border = 1>
<caption> Liste des personnes </caption>
<tr>
<th>id </th>
<th>nom</th>
<th>prenom</th>
<th>date Naissance</th>
<th>sexe</th>
<th>ville</th>
<th>comptence</th>
<th>photo</th>
</tr>
<?php while ($obj = mysqli_fetch_object($result)){ ?>
<tr>
<td> <?= $obj->id ?> </td>
<td><?= $obj->nom?></td>
<td><?= $obj->prenom?></td>
<td><?= $obj->dateNaissance?></td>
<td><?= $obj->sexe?></td>
<td><?= $obj->ville?></td>
<td><?= $obj->competence?></td>
<?php if (isset($obj->photo)) {?>
<td><img src="uploads/<?= $obj->photo?>" width =20 height = 20 >
<?php } ?>
<td>
<form name="editPerson" action="edit.php" method="POST">
<input type="hidden" name="id" value="<?= $obj->id ?>">
<input type="submit" name="editer" value="Edit">
</form>
</td>
</tr>
<?php } ?>
</table>
Explainations
You can't have an action='edit.php' as you will edit a specific user, not all of them. You need to specify in your action what user you want to edit. And it is mostly done with the ID of the user. So you action will look like this action='edit.php?id=1. And so, your method would be GET.
In your edit.php, you will have a $_GET['id'] variable that will contain the ID of the user to be edited. So you will have to first create a new query to search for this specific user.
You can then proceed on preparing the query.
$query = $connexion->prepare('SELECT * FROM users WHERE id = :id');
And then, executing the query with the id from the URI.
$query->execute(['id' => $_GET['id']]);
And cast the result to a variable to get the user.
Then, all you have to do in your page is a little bit of refactoring from your previous page. Meaning that there will be now a big <form> tag surrounding your <table> tag and the <td> tag will now contain <input value='<?php $user->id; ?>'> tag for example for the ID. And your edit buttons will now be a save button.
The method of the <form> in your edit?id=1 would be a POST method ot itself. So in the same page, you will be able to update the user. You can also cast the form to another page, like saveUser.php. Just be consistent from one solution to another in all your project.
<form method='POST' action='<?php echo $_SERVER['PHP_SELF']; ?>'>
Use this Code
<input type="submit" name="editer" value="Edit">
Instead of
<form name="editPerson" action="edit.php" method="POST">
<input type="hidden" name="id" value="<?= $obj->id ?>">
<input type="submit" name="editer" value="Edit">
</form>
And get the id value on edit.php file by using $_GET['id'].
Example for edit.php file:
$id = $_GET['id']
I have this code to show my table:
<form action="<?php echo $_SERVER['PHP_SELF'] ?>" method="POST">
<table cellspacing='0'>
<?php
if(isset($_GET["ordem"])){
if($_GET["ordem"] == 'descendente'){
echo "<thead><tr><th><a title='Ordenar por título' href='visualizarVoucher.php'>Utilizador</a></th>";
echo "<th>Email</th>";
echo "<th>Voucher</th>";
echo "<th>Categoria</th>";
echo "<th>Preço</th>";
echo "<th>Confirmação</th>";
echo "<th>Enviar mail</th>";
echo "</tr></thead>";
}
elseif($_GET["ordem"] == 'ascendente'){
echo "<thead><tr><th><a title='Ordenar por título' href='visualizarVoucher.php?ordem=descendente'>Utilizador</a></th>";
echo "<th>Email</th>";
echo "<th>Voucher</th>";
echo "<th>Categoria</th>";
echo "<th>Preço</th>";
echo "<th>Confirmação </th>";
echo "<th>Enviar mail</th>";
echo ("</tr></thead>");
}
}
else{
echo "<thead><tr><th><a title='Ordenar por título' href='visualizarVoucher.php?ordem=ascendente'>Utilizador</a></th>";
echo "<th>Email</th>";
echo "<th>Voucher</th>";
echo "<th>Categoria</th>";
echo "<th>Preço</th>";
echo "<th>Confirmação</th>";
echo "<th>Enviar mail</th>";
echo("</tr></thead>");
}
while($stmt->fetch()){
echo("<tbody>");
echo("<tr><td>$nomeUser</td>");
echo("<td>$email</td>");
echo("<td>$nomeVoucher</td>");
echo("<td>$categoria</td>");
echo("<td>$preco</td>");
echo("<td>$confirmacao</td>");
$content = file_get_contents($file,$filePDF);
echo("<td><INPUT TYPE='checkbox' NAME='mail[]' multiple='yes'></td>");
echo("</tr>");
echo("</tbody>");
}$stmt->close(); ?>
I have a checkbox in my table and I would like to know how can I get the values of each rows from the table when i selected the checkbox. I want to send email when the user selected multiple checkbox.
Thanks
It's possible that the code above is a snippet of a larger page, but if not:
You aren't actually wrapping your input elements in an HTML form tag. Doing so will cause the user agent (presumably a browser) to treat each input tag as something to be submitted to your backend form.
You should wrap the tables in a table element; tbody is a child of a table.
Regardless of the above:
It looks like your PHP code above will render the entire tbody each time the statement fetches a new row, which is a bit weird. I'd assume you only want to render a row containing mail options?
To the best of my knowledge, there is no multiple attribute allowed in a checkbox element. You may be thinking of the select element.
You are not setting a value attribute on your checkbox input tag. If the user actually submits a form, you'll either get a set of empty mail[] variables, or nothing at all, I'm not actually sure which.
Consider the code below: Note that the checkboxes have the same name attribute, but different values.
<form method="post">
<table>
<tbody>
<tr>
<td>
<input type="checkbox" name="mail[]" value="val1" id="mail-val1" />
<label for="mail-val1">Value 1</label>
</td>
</tr>
<tr>
<td>
<input type="checkbox" name="mail[]" value="val2" id="mail-val2" />
<label for="mail-val2">Value 2</label>
</td>
</tr>
<tr>
<td>
<input type="checkbox" name="mail[]" value="val3" id="mail-val3" />
<label for="mail-val3">Value 3</label>
</td>
</tr>
</tbody>
</table>
<input type="submit" />
</form>
Given this form, if the user selects all three of the checkboxes and submits, your server will receive a POST request with the payload:
mail[]=val1&mail[]=val2&mail[]=val3
Depending on how PHP parses that response (it's been about a decade since I've dealt with PHP), you'll probably have an array variable accessible to your application:
# mail == ["val1", "val2", "val3" ]
Hope this helps.
I have a form with rows which are populated from a table. Each row has a "checkbox" which the user can check or not.
When the form is submitted I want to be able to read which checkbox have been selected and insert the result in to a data table.
My code so far
FORM:
<form method="post" name="form1" action="<?php echo $editFormAction; ?>">
<table
<?php do { ?>
<tr>
<td>input type="text" name="InspectRoomNo" value="<?php print $row_InspectItems['AuditItemNo']; ?>"></td>
<td>php echo $row_InspectItems['AuditItem']; ?>td>
<td>input name="check[]" type="checkbox" ></td>
</tr>
<?php } while ($row_InspectItems = mysql_fetch_assoc($InspectItems)); ?>
<input type="submit" value="Insert record">
</table>
The insert: fetchs $Items from table
while($row = mysql_fetch_assoc($Items))
{
$array[] = $row['AuditItem'];
}
foreach($array as $id) {
$AuditItemID = mysql_real_escape_string($id);
if(isset($_POST['check'])){
$Checked = mysql_real_escape_string($_POST['check'][$row]);
}
}
The problem I am having is the returned values for all the checkbox is true, even if a checkbox was not selected.
Can anyone help me sort this issue.
Many thanks.
Do it like this:
if(!empty($_POST['check'])) {
foreach($_POST['check'] as $check) {
echo $check;
}
}
You should put the item id inside the checkbox name:
<td><input name="check[<?= $row_InspectItems['AuditItem']; ?>]" type="checkbox" /></td>
Then, you can simply iterate over it:
foreach ($_POST['check'] as $id => $value) {
// do stuff with your database
}
I'm assuming than whomever runs this script is trusted, because it would be easy to forge the list of ids; make sure the current user has permissions to update those records.
What is happening, is that only selected checkboxes get sent to the server, so you will see that your $_POST['check'] array (this is an array!) is smaller than the number of items you have displayed on the screen.
You should add your ID's so that you know what checkboxes got checked and adapt your php processing code to handle an array instead of a single value.
You are also overwriting your InspectRoomNo every row, so you should use an array there as well.
The form side would look something like:
<td><input type="text" name="InspectRoomNo[<?php echo row_InspectItems['AuditItemNo']; ?>]" value="<?php print row_InspectItems['AuditItemNo']; ?>"></td>
<td><?php echo $row_InspectItems['AuditItem']; ?></td>
<td><input name="check[<?php echo row_InspectItems['AuditItemNo']; ?>]" type="checkbox" ></td>
I have an html table I've updated to use checkboxes to be able to delete multiple files:
<table>
<thead>
<tr>
<th>Camera Name</th>
<th>Date Created</th>
<th>Video Size</th>
<th>Video Length</th>
<th>
<button type="submit" class="deletebutton" name="delete_video" value="Delete" title="Delete the selected videos" onClick="return confirm('Are you sure you want to delete?')">Delete</button><br>
<input type="checkbox" name="radioselectall" title="Select All" />
</th>
</tr>
</thead>
<tbody>
<?php
for($i=0;$i<$num_videos;$i++)
{
//do stuff
//Note: I'm looping here to build the table from the server
?>
<tr >
<td onclick="DoNav('<?php echo $url; ?>');">
<?php echo $result_videos[$i]["camera_name"]; ?>
</td>
<td onclick="DoNav('<?php echo $url; ?>');">
<?php echo setlocalTime($result_videos[$i]["video_datetime"]); ?>
</td>
<td onclick="DoNav('<?php echo $url; ?>');">
<?php echo ByteSize($result_videos[$i]["video_size"]); ?>
</td>
<td onclick="DoNav('<?php echo $url; ?>');">
<?php echo strTime($result_videos[$i]["video_length"]); ?>
</td>
<td>
<form name="myform" action="<?php echo htmlentities($_SERVER['REQUEST_URI']); ?>" method="POST">
<input type="checkbox" name="radioselect" title="Mark this video for deletion"/>
<input type="hidden" name="video_name" value="<?php echo $result_videos[$i]["video_name"]; ?>" />
</form>
</td>
</tr>
I started with first creating some jquery code to create a select all/deselect all button in the table heading and just a test to show I can find which boxes are checked. That all works:
//selectall checkboxes - select all or deselect all if top checkbox is marked in table header
$("input[name='radioselectall']").change(function()
{
if( $(this).is(':checked') )
{
$("input[type='checkbox']","td").attr('checked',true);
}
else
{
$("input[type='checkbox']","td").attr('checked',false);
}
});
//process checkboxes - which ones are on
$(".deletebutton").click(function() {
$("input[name='radioselect']:checked").each(function(i){
alert(this.value);
});
});
So the part where I'm stuck is I don't know where to go from here. I need to pass all the video_names of all the videos selected (with the checkboxes). video_name is part of a hidden field in my form. So I need to pass that to my php function when the delete button is selected. Not really sure how to tackle this. Hope this makes sense.
Simple solution maybe:
Change your checkboxes to have a value of 1 and a name of $result_videos[$i]["video_name"]; in the table rows, make the form encapsulate the whole table.
Then on submit you can do something like:
foreach ($_POST as $key => $value) {
//Delete $key (the name) where $value == 1
}
Your approach is fine if you want to access the hidden fields through jQuery at a given point but once you submit the form and lose the DOM, the PHP processing page will have no way to relate the selected checkboxes with the hidden fields as there is no consistent naming scheme.
One approach would be to use the loop counter to suffix the two in order to pair them up:
<input type="checkbox" id="radioselect_<?= $i ?>" title="Mark this video for deletion" value="1" />
<input type="hidden" id="video_name_<?= $i ?>" value="<?php echo $result_videos[$i]["video_name"]; ?>" />
This would be good if you want to relate more than the two fields. Otherwise, you could just use the video_name as the value of the checkbox, as Ing suggested.
