Question

i want to insert multiple values into a single field, i don't know how to achieve this i'm using a long-text data type field. And also tell me how to fetch these a value only one separate value at a time.

Answer 1

Insert Mutliple values in a single Field:
For inserting the flat no's in a single field, use implode and the values separated by comma.
$r=implode(",",$available);
$insert=mysql_query("insert into flatdetails(available) value ('$r')")
For retrieve the values from database use, explode to separate out all the values..
For Retrieve the values using
$i=explode(",",$r);
<?php
$select_tbl=mysql_query("select * from flatdetails",$conn);
while($fetch=mysql_fetch_object($select_tbl))
{
$r=$fetch->available;
$i=explode(",",$r);
echo $i[0]."</br>";
}
?>

Answer 2

As far as my knowledge goes, MySQL does not have any data types that could help your use case. Well, actually it has a "set" data type, but it only allows for up to 60-something members if I recall correctly.
You can try using BLOB as your column type and store serialized data in there (i.e. JSON, protocol buffers).
However, I would recommend that you re-evaluate your DB's design. You're breaking the first normal form, and it's a sign that you're doing something wrong.

Answer 3

Use json_encode to encode the content and then store it in db field and when you retrieve the value then use json_decode ( Same like wordpress )

Answer 4

Its not a good idea to store multiple values into a single column. If you really want to do that store your strings as coma separated. And when reading back from database you can use php explode function. Php explode
I'll give you another option to store
Assume your strings are str1,str2,str3
First if you use your method it will be like below. which is not a good idea i think.
I think following is the good method

Answer 5

I think you should use Array and Implode functionality of PHP. Create an array and implode it by comma. For example---
Suppose you have three fields then get values of these input fields and make an array.
$arr = array(); // Declare an array
$arr[] = $_POST['FirstField'];
$arr[] = $_POST['SecondField'];
$arr[] = $_POST['ThirdField'];
// As more as you have input fields.
Then make it a string like
$insertValue = implode(',',$arr); // This will create a string containing all your fields values and you can save it in single field.
Just use this single variable in your insert query.
Hope this will help you.

Answer 6

db connect file with PDO save as config.php
<?php
$dbhost = 'localhost';
$dbname = 'clsrepair';
$dbuser = 'root';
$dbpass = '';
try {
$db = new PDO("mysql:host={$dbhost};dbname={$dbname}",$dbuser,$dbpass);
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
}
catch(PDOException $e) {
echo "Connection error: ".$e->getMessage();
}
?>
then in you desire file:
if(isset($_POST['your_form']))
{
try {
$leavingEquipment = implode(', ', $_POST['leavingEquipment']);
$statement = $db->prepare("INSERT INTO orderForm (orderNo,leavingEquipment) VALUES (?,?)");
$statement->execute(array($_POST['orderNo'],$leavingEquipment));
$success_message = "Order's has been inserted successfully.";
}
catch(Exception $e) {
$error_message = $e->getMessage();
}
}
