Hello, 

I'm using a relatively complicated html/javascript code in some of my questions, and it appears that there is a limit on the number of lines of code that are possible. Is there any way to increase this limit? 

In the database this field is of type "text".
 

The maximum amount of data that can be stored for each data type is approximately:
TEXT 65,535 bytes ~64kb

But consider: Unicode characters may use more than one byte.
And this, too

The maximum size of a 

Code:

BLOB

 or 

Code:

TEXT

 object is determined by its type, but the largest value you actually can transmit between the client and server is determined by the amount of available memory and the size of the communications buffers. You can change the message buffer size by changing the value of the 

Code:

max_allowed_packet

 variable, but you must do so for both the server and your client program.

Place the code in a function in your custom.js file and call it from the question.

@Joffm: thank you. That's what I suspected/feared.
@tpartner: that's a great idea! I was thinking about doing something like that, but it's good to hear from the expert that it's possible.

Else : on mysql : you can set this column as LONGTEXT .
It's OK for PHP code, and you have a lot more space.
