how to insert values from checkbox to MYSQL Database? - php

<table width="200" border="0">
<tr>
<td><p>
<?php while($row1 = mysql_fetch_array($res)){ ?>
<label>
<input type="checkbox" name="module" value="<?php echo $row1['MID']?>" id="<?php echo $row1['MID']?>">
<?php echo $row1['ModuleName']?></label>
<br>
<?php }?>
</p></td>
</tr>
</table>
I use this code to outout the checkboxes,and the checkboxes appear allright.
I m not sure about how,the data can be saved to the MYSL table.
the table i drew is in the form:
student_module{studentID,ModuleID}
what is the code i should write to enter the data to that table.
One student can enroll to many modules.

Using ajax functionality:
By clicking on checkbox collect the value of studentID and ModuleID and pass to the ajax method and then in your server end page, you can update db record.
Without ajax functionality
Post the form when user clicking on checkbox or put a save button below to submit the form on a PHP page and then you can collect all your values and update db accordingly.

<input type="checkbox" name="chk1[]" value="" ><?php echo $row1['ModuleName']?>
if(isset($_POST['submit']))
{
$checkbox1 = $_POST['chk1'];
$selected_checkbox = "";
foreach ($checkbox1 as $checkbox1)
{
$selected_checkbox .= $checkbox1 . ", ";
}
$selected_checkbox = substr($selected_checkbox, 0, -2);
// now here in your insert query take mid='".$selected_checkbox."';
}

Sending a SQL command with one click of an HTML button through PHP

So, I have a basic PHP site that brings up a list of salespeople from a MySQL server when a selection from a drop-down box is submitted. I've set up a button to appear next to each result, and I want a php script to run when the button is clicked using MySQL data from that specific result. Everything works except the button that runs the second MySQL query. Here's an example of the table after the first query:
<table border="1">
<tr>
<td>Last name</td>
<td>First Name</td>
<td>Job Title</td>
<td>City</td>
<td>Client List</td>
</tr>
<tr>
<td>Bondur</td>
<td>Gerard</td>
<td>Sale Manager (EMEA)</td>
<td>Paris</td>
<td>
<form method="POST" action="empLookup.php">
<input type="submit" name="empLookup" value="Look up clients"
</td>
</tr>
</table>
By clicking on the button I would run a MySQL command like 'SELECT clients FROM blah WHERE employeeNumber = ?'
I don't have a problem with any of this except passing the value from the button to the PHP script.
This is what my PHP code looks like for handling the form submission and display of results. The button(s) in question are in the HTML table in the foreach loop.
<?php #this is the default php file for looking up Employees
$page_title = 'Our Associates by City';
require ('./pdoConn.php');
$sql = "SELECT DISTINCT city from Offices";
echo '<h1>Our Associates by City</h1>';
Type in a Name to view Years</a><br>';
//create the form
echo 'Please select a year: <br>';
echo '<form action="index.php" method="post">';
echo '<select name= "city">';
foreach($conn->query($sql) as $row)
{
//each option in the drop down menu is each and every year
//brought up by the query
echo '<option value ="'. $row['city'].' ">'. $row['city']. '</option>';
} //end of foreach
echo '</select>'; //end drop down menu
//now to create the submit button
echo '<br><input type="submit" name="submit" value="List"><br>';
echo '</form>'; //end of form
//This if statement runs when the submit button is clicked
if ($_SERVER[REQUEST_METHOD] == 'POST')
{
$flit = $_POST[city]; //the city variable from the HTML form will be used
echo '<br><br>';
$sql2 = "SELECT employeeNumber,lastName,firstName,jobTitle,city
FROM Employees,Offices
WHERE Employees.officeCode = Offices.officeCode AND city = ?";
$stmt = $conn->prepare($sql2);
$stmt->execute(array($flit));
$rows = $stmt->fetchAll(PDO::FETCH_ASSOC);
echo 'Contact any of our local staff: <br>';
//create a table of employees
echo '<table border="1"><tr><td>Last name</td><td>First Name</td>';
echo '<td>Job Title</td><td>City</td></tr>';
//time to populate the table, this loop runs for each entry
foreach($rows as $r)
{
echo '<tr><td>'.$r[lastName].'</td><td>'.$r[firstName].'</td><td>';
echo $r[jobTitle].'</td><td>'.$r[city].'</td><td>';
echo '<form method="POST" action="empLookup.php">';
//now to make the button which will search the employee's client list
echo '<input type="submit" name="empLookup" value="Look up clients"</td></tr>';
} //end foreach
echo '</table>';
} //end if server request post thing
?>
I does not completely understood your exact requirement but I think you want employee number into your button if this is your requirement then you can simply check this code
`echo '<input type="submit" name="empLookup" value="'.$r['emp_id_from_database'].'"</td></tr>';`
From your html code, your form looks empty.
You need to add the data to your html form. If you want to avoid the user to see you can use fields. Like it was in the comments said, use $variableName instead of ? in your query. Don't forget use \"$variableName\" to avoid mysql injections.
I took a second reading of your code: You realy should read a php book completly before you program stuff for productive company websites. There are beginner mistakes in your code. And some beginner mistakes leads to insecure websites. I hope this doesn't look an offense, but like an advise.

Cannot insert checkbox value into database

Hello i'm a newbie in PHP language. So I hope u guys can be simple with me. I need to create like a attendance system for a meeting. Now I was stuck at one part. I need to add a staff from a department for every created meeting event. The staff name was already appear when I click from dropdown menu for every department that retrieve from database. Now I tried to select from the checkbox staff that I want to add with the meeting id. But nothing is happened when I click the submit button after checked the staff name. I want to add to a new table with the meeting id. display.php is code I create to appear the staffname and to check the checkbox and retrieve the record from user table . The checkbox.php is for insert the checked checkbox to a table meetingstaff. Please anyone help me..
Here I attached my PHP code
display.php
<label>Reference No:</label>
<label id="attach"><?php echo $_GET["refno"]; ?></label>
<form action="display.php?refno=<?php echo $_GET["refno"]; ?>" method="post">
<?php do { ?>
<form action="checkbox.php?refno=<?php echo $_GET["refno"]; ?>" method="post">
<tr >
<td><div align="center"><input name="chkl[]" type="checkbox" id="checkbox[]" value="<? echo $row_Recordset4['staffname']; ?>"></td>
<td><div align="center"><?php echo $row_Recordset4['staffname']; ?></div></td>
<td><div align="center"><?php echo $row_Recordset4['staffno']; ?></div></td>
</div></td>
</tr>
<?php } while ($row_Recordset4 = mysql_fetch_assoc($Recordset4));?>
checkbox.php
<label>Reference No:</label>
<label id="attach"><?php echo $_GET["refno"]; ?></label>
<?php
$checkbox1 = $_POST['chkl'];
if($_POST["Submit"]=="Submit")
{
for ($i=0; $i<sizeof($checkbox1);$i++) {
$query="INSERT INTO meetingstaff (staffname, staffno) VALUES ('".$checkbox1[$i]."')";
mysql_query($query) or die (mysql_error());
}
echo "Record is inserted";
}
?>
You need to INSERT a second parameter, or remove , staffno from the first part of the INSERT statement. You are passing just one value, but instructing for two columns.
So change your:
INSERT INTO meetingstaff (staffname, staffno) VALUES ('".$checkbox1[$i]."')
to either
INSERT INTO meetingstaff (staffname) VALUES ('".$checkbox1[$i]."')
or perhaps
INSERT INTO meetingstaff (staffname, staffno) VALUES ('".$checkbox1[$i]."', ".$i.")

Retrieve POST checkbox data from form if they exist

Hello knowledgeable people. I am having trouble retrieving checkbox data from form. I have a site in which user can add checkboxes themselves, so I am writing them out like this:
<table style="padding:10px;">
<?php
$query_boolean = $DB->prepare("SELECT * FROM moduls WHERE type='boolean'") or die(mysql_error());
$query_boolean->execute();
while (($row = $query_boolean->fetch()) != false)
{
?>
<tr>
<td>
<?php echo $row->name ?>:
</td>
<td>
<?php
$s = "";
$s .= sprintf('<input type="checkbox" class="textbox" name="boolean_%s" value="yes">%s', $row->id, Yes);
$s .= sprintf('<input type="checkbox" class="textbox" name="boolean_%s" value="no">%s', $row->id, No);
echo $s;
?>
</td>
</tr>
<?php
}
?>
</table>
Now I have an advanced search in which I have to chech through every checkbox to see what has been selected (ether none, Yes, No, or both). How can I get the info from every checkbox in variables? Thank you so much!
To get POST data from checkboxes they must have attribute
checked="checked"
EDIT:
If you have 2 checkbox as this..
<input type="checkbox" checked="checked" class="textbox" name="boolean_yes" value="yes">
<input type="checkbox" class="textbox" name="boolean_no" value="no">
When you submit your form the checkbox with attribute checked will be sent as POST and the one without checked attribute will not be sent..
if(isset($_POST['search'])) {
$all_checked = array();
foreach($_POST as $key=>$value){
if(strpos($key, "boolean_") > -1){
$all_checked[$key] = $value;
}
}
var_dump($all_checked);
}
This way you will get inside $all_checked array all marked boxes.. All others checboxes are not marked!
if you want to get checkbox value then use checkbox name as array
<input type="checkbox" name="email1[]" value="">
an get it on another page by
<?php
$var2 = $_POST['email1'];
$v=implode(",",$var2);
echo $v;
?>
try it

Looping through an array of checkbox

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>

Retrieve data from mysql and update them accordingly

I want to retrieve data from my MySQL database and display it as a table (I don't mind any style, but preferred as a table). Then the data should display with a radio button or a normal button which update that specific row and changing a single column in that row to Active (Status making Active).
I have started it, but I still have issues with adding a radio button or a button. Then I thought of displaying the information in a table which inside a form. This form will have each radio buttons, when the person select that radio button and press submit. The data should be updated in the MySQL database.
Can someone guide me about this? I'm a bit confused. I'm confused because I have to add a form and in that form I have to add a table and all this stuff should be in a php file.
on formpost.php page you can do something like this for handling the list array you received from the previous page:
<?
$list = $_POST['list'];
foreach ($list as $key => $list_php)
{
$query1 = "SELECT * FROM `stu_entry` WHERE `stu_entry`.`Student_No` = '$list_php' AND `stu_entry`.`Out_Time` = '0000-00-00 00:00:00'";
$result1 = mysql_query($query1);
$row1=mysql_fetch_array($result1);
//whatever you want to do
}
?>
I forgot to tell you something in the previous post. In the form page, lets say you have 100 rows with 100 checkboxes. It would be nasty to manually check or uncheck all of them. As an alternative you could append a little script at the end of the page to handle the checking/ unchecking process for you:
<script>
function checkAll(field)
{
for (i = 0; i < field.length; i++)
field[i].checked = true ;
}
function uncheckAll(field)
{
for (i = 0; i < field.length; i++)
field[i].checked = false ;
}
function countChecks(form){
var t=0;
var c=form['list[]'];
for(var i=0;i<c.length;i++){
c[i].checked?t++:null;
}
return t;
}
</script>
<input type="button" name="CheckAll" value="Check All"
onClick="checkAll(document.formpost['list[]'])">
<input type="button" name="UnCheckAll" value="Uncheck All"
onClick="uncheckAll(document.formpost['list[]'])">
<i>with selected: </i>
<select name="submit_mult" id="submit_mult">
<option value="todo1">Action 1 </option>
<option value="todo2">Action 2 </option>
</select>
<input type="button" name="go" value="Go" onClick='if(countChecks(this.form)>0) {if(confirm("are you sure you want to \""+document.getElementById("submit_mult").options[document.getElementById("submit_mult").selectedIndex].text+" "+countChecks(this.form)+" items selected"+"\"")) {document.getElementById("referenceToSomeHiddenElement").value=document.getElementById("submit_mult").options[document.getElementById("submit_mult").selectedIndex].value;document.getElementById("formpost").submit();}} else alert("you have not selected any item!!")' >
Tell me if you need more help on this.
I first specify a MySQL command which in return gives me an array. I use a while statement to do something to each item in the array. The array is populated with the field name and the field contents.
$mysql = mysql_query("SELECT * FROM table");
while ($array = mysql_fetch_array($mysql))
{
$output .= '<form>Row: ' . $array['fieldname'] . ' <input type="button" value="Update" /></form>';
}
This extracts all rows from the table and adds a form to the variable $output for every result. I'm unsure of how you want to update your database, so you will have to look into it. You can use GET and POST methods.
Go ahead and try something like this. And tell me if that worked:
<p><b>your page name</b></p>
<form name="formpost" id="formpost" action="formpost.php" method="POST">
<table border="2" cellpadding="5" cellspacing="1" style="border-collapse: collapse" bordercolor="#999999" width="800">
<tr>
<td><b>Sno.</b></td>
<td><b>Field name1</b></td>
<td><b>Field name2</b></td>
<td><b>Field name3</b></td>
<td><b>Field name4</b></td>
<td><b>Field name5</b></td>
<td><b>Field name6</b></td>
<td><b>Field name7</b></td>
</tr>
<?
$sorting="";
if($orderby!="" && $direction!="") $sorting=" ORDER BY $orderby $direction";
$query = "SELECT * FROM table WHERE something = 'something' $sorting";
$result = mysql_query($query);
?>
<tr>
<?
$i=0;
while ($row = mysql_fetch_array($result))
{
$i++;
?>
<td><input type="checkbox" name="list[<?echo $i?>]" id="list[]" value="<?echo $row['some_primary_field_id']?>"><?echo $i?></td>
<td><?echo $row['Field1']?></td>
<td><?echo $row['Field2']?></td>
<td><?echo $row['Field3']?></td>
<td><?echo $row['Field4']?></td>
<td><?echo $row['Field5']?></td>
<td><?echo $row['Field6']?></td>
<td><p align="center">
<?
echo "<input title='button' name='change this row' value='Some Button' type='button' onClick=\"if(confirm('Press OK to change status to confirm')) {document.getElementById('someid').value='".$row['Field1']."';document.getElementById('formpost').submit();}\"/>";
?>
</td>
</tr>
<input type='hidden' name="hiddenlist[<?echo $i?>]" id="hiddenlist[]" value="<?echo "some boundry condition ".$row['Field2']?>">
<?
} //end of while
?>
</table>
</form>
