TextField rows

Posted on 2004-09-21

Is there a way to restrict the user from entering more than a certain number of rows in a TextField? I would like the user to be able to enter only 4 lines of data and that too with a specified number of columns.

I have set the properties in Dreamweaver, Num Lines to 4, but that does not seem to restrict the user.

Any idea what i am doing wrong or can do differently to do this right???

Hi KM,

>>Num Lines to 4, but that does not seem to restrict the user<<
You are right, it doesn't. It only tells the page how big you want the textarea to be.

A textarea can't be restricted through HTML code, you would need some scripting to do that.
While in the proccess of getting you such script I realized there is a much simpler solution for you:


>> I would like the user to be able to enter only 4 lines of data and that too with a specified number of columns<<

If you are this sure about the exact amount of information you spect from your users, then you should go with one line textfields:

*************************
<input name="textfield" type="text" size="50" maxlength="50">
  <br>
  <input name="textfield2" type="text" size="50" maxlength="50">
  <br>
  <input name="textfield3" type="text" size="50" maxlength="50">
  <br>
  <input name="textfield4" type="text" size="50" maxlength="50">
*************************

These are four lines of text input limited to 50 chars each. Easy and no scripting required (at least for this part).

Best regards,

Esopo.

Just so I can understand the problem a little better, what kind of data are the users entering that it must be entered in one text box? Unless you have some out of the ordinary situation, Esopo's suggestion is probably the best way to do it using HTML only.

The data being entered is just plain text...stored as Memo in access.

If the data is being written to the Access database, I would just follow what Esopo wrote. Next, the Submit button should link to a page that processes the data, like process.asp (I'm assuming you're using ASP pages since you are working with the Access database). The VBScript in this page would take the four strings and combine them into one string. Then you just connect to your database and write the single string into the Memo field.  If successful, process.asp will display some kind of "Your data was successfully entered." or whatever you want to say.

It's been many, many years since I've even looked at ASP, so maybe someone else can provide you with the code. If you're working with the database, you may already know how to do this.

Hope this helps!
