Undefined index

[june_c21]

i encounter this problem when i trying to run the php scripts. what's wrong?

 

for($i=1;$i<9;$i++)

  {

  $eq_id[$i] = $i;

  $var1 = $i . "equipment";

$equipment[$i] = $_POST[$var1];

  $var2 = $i . "viscosity";

  $viscosity[$i] = $_POST[$var2];

  $var3 =  $i . "water";

  $water[$i]  = $_POST[$var3];

  $var4 =  $i . "tan";

  $tan[$i]    = $_POST[$var4];

  $var5 =  $i . "oil";

  $oil[$i]    = $_POST[$var5];

  $var6 =  $i . "wear";

  $wear[$i]    = $_POST[$var6];

  $var7 =  $i . "remarks";

  $remarks[$i]  = $_POST[$var7];

  }

 

the red one is the error

[cooldude832]

first use the [ code] brackets, secondly you need to give us a line number and the exact error if u want help

[june_c21]

the red line is the error

Try the following code instead, don't need to use $i for the array indexes :-o (it automatically indexes if you use just empty brackets, like so)

for($i=1;$i<9;$i++)
  {
  $eq_id[] = $i;
  $equipment[] = $_POST[$i."equipment"];
  $viscosity[] = $_POST[$i."viscosity"];
  $water[] = $_POST[$i."water"];
  $tan[] = $_POST[$i."tan"];
  $oil[] = $_POST[$i."oil"];
  $wear[] = $_POST[$i."wear"];
  $remarks[] = $_POST[$i."remarks"];
  }

There is a purpose to defining an index, if you are to resort the array you can resort by your defined indexing (as it will carry the indexes with the new sort)

Ok, those are the post variables. Where are you getting the post variables from, cause I'm a bit scared of a form that submits well over 50 variables through the post method at once xD

[cooldude832]

lets see the form

why is over 50 post variables an issue?

Use [ code ] [ /code ] tags please.

 

I'm lost on the following variables:

 

$myrow[1] and $myrow[0], what are those variables supposed to give you?

[cooldude832]

if your lost then don't try and help, you will need to show what these outputs, also if you are pulling dynamic fields off a database with dynamic names (not exactly ideal) then you will need to consider this in the process page

No, I said I'm lost on what the outputs of those variables are supposed to be. And as far as dynamic content, I agree... I mean, you don't know exactly how many rows you'd be returning (unless it was index, unique) or there was a LIMIT attached to the end, etc... or of course, you use mysql_num_rows for that matter.

[cooldude832]

the post names are transparent because they are transported you can do a foreach($_POST as $key => $value) and return those keys, and discovery all keys that match a regex with that textual suffex, and then use those, but that only complicates things

[june_c21]

this is how the form look like

 

[attachment deleted by admin]

[cooldude832]

that ain't what we are talking about.

 

The source code of the form inputs is what I am talking about.

What is outputted to the browser, not the php as your raw php creates dynamic output.

Notice Undefined index: 1viscosity in C:\Web\lubrication1\add_phase2.php on line 15

 

You can translate this as "POST variable 1viscosity was not sent to the script"

 

Note that that's only accurate for your script, it's not a general translation for "undefined index".  So you need to work out why it's not sent.  The best way to work that out is to look at the generated form, which is what the others are asking for.
