Your code misses :

1. Form tag
2. Single quote never evaluates/expand variables.
3. No submit buttons.

Thanks Atli & Adatapost for your responses.

Adatapost,
What I intend to do is to insert a new record after customising the display data ( by click edit button).. so, I need to change "update" to "insert"..am I?

& how can the id be increased based on the highest id in the table?

thanks

Add another submit button with value="Insert" and name="cmd". Compare value of $cmd and if it is "Insert" then write code to insert a record.

hello all,
thanks for your input

•

& how can the id be increased based on the highest id in the table?

what I mean here is to enable an ID auto increment whenever we insert a new record to the table.
Do I have to query the maximum number in that table,
then ID++.
Is it correct? any proper syntax?
thanks

You can simply add the AUTO_INREMENT option to the column that is supposed to incremented, and leave it out of the INSERT query.

 Help with Code Tags 
 sql Syntax (Toggle Plain Text) 
CREATE TABLE test (
  `id` INT UNSIGNED NOT NULL AUTO_INCREMENT,
  `value` VARCHAR(255) NOT NULL,
  PRIMARY KEY(`id`);
);
 
INSERT INTO test(`value`)
VALUES ('First'), ('Second'), ('Third');
 
SELECT * FROM test;
+----+--------+
| id | value  |
+----+--------+
|  1 | First  |
|  2 | SECOND |
|  3 | Third  |
+----+--------+
CREATE TABLE test (
  `id` Int Unsigned Not Null Auto_Increment,
  `value` VarChar(255) Not Null,
  Primary Key(`id`);
);

INSERT INTO test(`value`)
VALUES ('First'), ('Second'), ('Third');

SELECT * FROM test;
+----+--------+
| id | value  |
+----+--------+
|  1 | First  |
|  2 | Second |
|  3 | Third  |
+----+--------+

HI adatapost,
I am sorry for coming to this thread again
several questions to ask:

•

$flag="disabled=\"disabled\"";

to enable the textboxes after click edit, can we code like this ?

 Help with Code Tags 
 php Syntax (Toggle Plain Text) 
   $unflag="enabled=\"enabled\"";
   $unflag="enabled=\"enabled\"";

I have tried this but it doesn't work.

when click the EDIT button, the value in textbox
remains..& can be editted.
currently the value is set to empty = $flag="";

thank you

There is no enabled attribute. There is no need for it.
If the tag isn't specifically marked as disabled, it will be enabled.
So to enable it, simply remove the disabled attribute, as adatapost demonstrated.
