I have created a database with a table and that table with one column of varchar datatype.
Now I want to delete the rows without using
DELETE FROM songs_list WHERE songs_name = 'Shakira Waka Waka'
This is so because I cannot write the name of the checkbox with spaces. For example:
<?php for ($printedsno=1; $printedsno <$noio+1 ; $printedsno++){?>
<?php while($row = mysqli_fetch_assoc($query7) ):?>
<input type="checkbox" name="<?php echo "cb".$row['songs_name'];?>"/>
<?php echo $printedsno?> <?php echo $row['songs_name']?></br>
<?php
break;
endwhile;
}
?>
Here We can not write the checkbox name as <?php echo "cb".$row['songs_name'];?>
That is why I want to use a psudo-Column. But For the Psudo-Column We can not be able to use a where clause beacause this column does'nt exist.
I want to delete the row from table with only column.
<?php
include 'database.php';
$noofsongs = "select * from songs_list";
$query8 = mysqli_query($con, $noofsongs);
$noio = mysqli_num_rows($query8);
$flag = 0;
$del = 0;
$row = mysqli_fetch_assoc($query8);
$song_names = $row['songs_name'];
if(isset($_POST['deletethis'])){
for($j=1; $j<=$noio ;$j++){
while($row = mysqli_fetch_assoc($query8) ){
if (isset($_POST['cb'.$song_names])){
$deletesongsquery = "DELETE FROM `songs_list` WHERE `songs_name` = $song_names" ;
$query4 = mysqli_query($con, $deletesongsquery);
if($query4){ $del++;}
$flag = $flag + 1;
}
}
}
if($del != $flag){echo "Can Not Be Deleted All Selected Songs.";}
else{echo "Deleted $del Selected Songs.";}
}
?>
Can anyone help me in this??
I have to create a program which allows users to delete an update lecturers from a lecturers table. For some reason the table which my program displays is not accurate(e.g older values than current table). And i cannot delete or update. I have been stuck on this for quite a while and apologies if it is a simple solution i am only a beginner.

I want to insert foreign key value in table.I have two tales employee(employee_id) and attendance. Here employee_id is foreign key in attendance table.
I try a lot but value is not inserted.
Here is my code
if(isset($_POST['submit']))
{
$date = date('Y-m-d',strtotime($_POST['daily_date']));
$in = $_POST['daily_in'];
$l_out = $_POST['lunch_out'];
$l_in = $_POST['lunch_in'];
$out = $_POST['daily_out'];
$emp_remarks = $_POST['remarks'];
$sql = "INSERT INTO attendance (atten_id,daily_date,daily_in,lunch_out,lunch_in,daily_out,remarks,employee_id)
VALUES('NULL','$date','$in','$l_out','$l_in','$out','$emp_remarks','".$_REQUEST['employee_id']."')";
$res = mysql_query($sql);
if ($res > 0) {
echo "inserted";
}
If I run below code then
if(isset($_POST['submit']))
{
$date = $_POST['daily_date'];
$in = $_POST['daily_in'];
$l_out = $_POST['lunch_out'];
$l_in = $_POST['lunch_in'];
$out = $_POST['daily_out'];
$emp_remarks = $_POST['remarks'];
if(isset($_REQUEST['employee_id']))
{
echo "Employee Id" .$_REQUEST['employee_id'];
}
else {
echo "Smoething went wrong";
}
$sql = "INSERT INTO attendance (atten_id,daily_date,daily_in,lunch_out,lunch_in,daily_out,remarks,employee_id)
VALUES
('NULL','$date','$in','$l_out','$l_in','$out','$emp_remarks','".$_REQUEST['employee_id']."')";
its gives
Smoething went wrong not inserted error
Before inserting try this , try this to check whether value was passed or not.
isset($_REQUEST['employee_id'])
{ echo "Employee Id" .$_REQUEST['employee_id'];
} else {
echo "Smoething went wrong";
}
I have a partner table and I need to send reply via SMS. So my table contains firm name, city, mobile and pincode. If someone sends me a pin code via SMS, I want to get back to the customer with the 2 or 3 records (Multiple). With this code I am able to send only one record.
$sql = "SELECT * FROM reg_dealer WHERE pincode = '$myvalue'";
$q = mysql_query($sql);
$rows= mysql_num_rows($q);
$res= mysql_fetch_array($q);
$firm_name=$res['firm_name'];
$city=$res['city'];
$mobiledealer=$res['mobile'];
$pincode=$res['pincode'];
if($res['pincode']=='')
{
$mobile = $_GET['mobile'];
$reply_message = "Greeting. We will get back to you soon on the nearest Partner details.";
$reply_message1 = urlencode($reply_message);
mysql_query("INSERT INTO history(sender,message,datetime,datenew,code,status,reply_message,url)VALUES('$mobile','$message','$datetime','$datenew','$number','Dealer Does Not Exist','$reply_message','$s')");//insert data in to table
}
// part 2
else
{
$mobile = $_GET['mobile'];
$reply_message = "Greetings. Please find the nearest Partner - ".$firm_name.", ".$city.", +".$mobiledealer.".";
$reply_message1 = urlencode($reply_message);
mysql_query("INSERT INTO history(sender,message,datetime,datenew,code,status,reply_message,url)VALUES('$mobile','$message','$datetime','$datenew','$number','Dealer Details Sent','$reply_message','$s')");//insert data in to table
}
Use while loop.
$sql = "SELECT * FROM reg_dealer WHERE pincode = '$myvalue'";
$q = mysql_query($sql);
$rows= mysql_num_rows($q);
while($res= mysql_fetch_array($q))
{
$firm_name=$res['firm_name'];
$city=$res['city'];
$mobiledealer=$res['mobile'];
$pincode=$res['pincode'];
if($res['pincode']=='')
{
$mobile = $_GET['mobile'];
$reply_message = "Greeting. We will get back to you soon on the nearest Partner details.";
$reply_message1 = urlencode($reply_message);
mysql_query("INSERT INTO history(sender,message,datetime,datenew,code,status,reply_message,url)VALUES('$mobile','$message','$datetime','$datenew','$number','Dealer Does Not Exist','$reply_message','$s')");//insert data in to table
}
// part 2
else
{
$mobile = $_GET['mobile'];
$reply_message = "Greetings. Please find the nearest Partner - ".$firm_name.", ".$city.", +".$mobiledealer.".";
$reply_message1 = urlencode($reply_message);
mysql_query("INSERT INTO history(sender,message,datetime,datenew,code,status,reply_message,url)VALUES('$mobile','$message','$datetime','$datenew','$number','Dealer Details Sent','$reply_message','$s')");//insert data in to table
}
}
Update with new requirement:
$mobile = $_GET['mobile'];
$sql = "SELECT * FROM reg_dealer WHERE pincode = '$myvalue'";
$q = mysql_query($sql);
$rows= mysql_num_rows($q);
while($res= mysql_fetch_array($q))
{
$firm_name=$res['firm_name'];
$city=$res['city'];
$mobiledealer=$res['mobile'];
$pincode=$res['pincode'];
if($res['pincode']=='')
{
$reply_message .= "Greeting. We will get back to you soon on the nearest Partner details.";
mysql_query("INSERT INTO history(sender,message,datetime,datenew,code,status,reply_message,url)VALUES('$mobile','$message','$datetime','$datenew','$number','Dealer Does Not Exist','$reply_message','$s')");//insert data in to table
}
// part 2
else
{
$reply_message .= "Greetings. Please find the nearest Partner - ".$firm_name.", ".$city.", +".$mobiledealer.".";
mysql_query("INSERT INTO history(sender,message,datetime,datenew,code,status,reply_message,url)VALUES('$mobile','$message','$datetime','$datenew','$number','Dealer Details Sent','$reply_message','$s')");//insert data in to table
}
}
if (isset($reply_message) && $reply_message != '')
{
$reply_message1 = urlencode($reply_message);
if($res['pincode']=='')
{
mysql_query("INSERT INTO history(sender,message,datetime,datenew,code,status,reply_message,url)VALUES('$mobile','$message','$datetime','$datenew','$number','Dealer Does Not Exist','$reply_message1','$s')");//insert data in to table
}
// part 2
else
{
mysql_query("INSERT INTO history(sender,message,datetime,datenew,code,status,reply_message,url)VALUES('$mobile','$message','$datetime','$datenew','$number','Dealer Details Sent','$reply_message1','$s')");//insert data in to table
}
}
You are fetching only single record because you are not using any type of loop for getting multiple records.
Use while loop:
while($res= mysql_fetch_array($q))
{
//put your below inside the loop
}
I'm working on a project where a user can click on an item. If the user clicked at it before , then when he tries to click at it again it shouldn't work or INSERT value on the DB. When I click the first item(I'm displaying the items straight from database by id) it inserts into DB and then when I click at it again it works(gives me the error code) doesn't insert into DB. All other items when I click at them , even if I click for the second, third, fourth time all of it inserts into DB. Please help guys. Thanks

Your problem is here :
$match = "SELECT user_id, match_id FROM match_select";
$row1 = mysql_query($match)or die(mysql_error());
while ($row2 = mysql_fetch_assoc($row1)) {
$user_match = $row2["user_id"];
$match = $row2['match_id'];
}
You are not checking it correctly. You have to check if the entry in match_select exists for the user_id and the match_id concerned. Otherwise, $match would always be equal to the match_id field of the last inserted row in your database :
$match = "SELECT *
FROM `match_select`
WHERE `user_id` = '<your_id>'
AND `match_id` = '$test_id'";
$matchResult = mysql_query($match)or die(mysql_error());
if(mysql_num_rows($matchResult)) {
echo "You have already bet.";
}
By the way, consider using PDO or mysqli for manipulating database. mysql_ functions are deprecated :
http://www.php.net/manual/fr/function.mysql-query.php
validate insertion of record by looking up on the table if the data already exists.
Simplest way for example is to
$query = "SELECT * FROM match_select WHERE user_id = '$user_id'";
$result = mysql_query($query);
if(mysql_num_rows($result) > 0)
{
// do not insert
}
else
{
// do something here..
}
In your form you have <select name='test[$id]'> (one for each item), then when you submit the form you are getting $tests = $_POST["test"]; You don't need to specify the index in the form and can simply do <select name='test[]'>, you can eventually add a hidden field with the id with <input type="hidden" value="$id"/>. The second part is the verification wich is not good at the moment; you can simply check if the itemalready exist in the database with a query
