Counting help

[yoki]

OK

I have a PHP page that generates an HTML table with 10 rows and 7 columns with textboxes in each cells.

For example:

1. [co_aut1_last_name] | [co_aut1_first_name] | [co_aut1_institution] | [co_aut1_city] | [co_aut1_country]
   2.[co_aut2_last_name] | [co_aut2_first_name] | [co_aut2_institution] | [co_aut2_city] | [co_aut2_country]
   3.[co_aut3_last_name] | [co_aut3_first_name] | [co_aut3_institution] | [co_aut3_city] | [co_aut3_country]
   .
   .
   .
   10.

Now, this is where I'm stuck at programming. I want to be able to count how many co-authors were entered since there is no limit on how many they enter. Would someone have an idea on how to implement this? I thought maybe checking the array_keys but then what? Anyone? 😕

Post your code so I can get a better understanding of what you're doing and want.

Put them in an array, and then use the count() function on the array.

co_aut1_last_name
co_aut1_last_nameinitvalue
co_aut1_first_name
co_aut1_first_nameinitvalue
co_aut1_institution
co_aut1_institutioninitvalue
co_aut1_city
co_aut1_cityinitvalue
co_aut1_country
co_aut1_countryinitvalue
co_aut2_last_name
co_aut2_last_nameinitvalue
co_aut2_first_name
co_aut2_first_nameinitvalue
co_aut2_institution
co_aut2_institutioninitvalue
co_aut2_city
co_aut2_cityinitvalue
co_aut2_country
co_aut2_countryinitvalue

Ok how do I get the following fields only using preg_match?

co_aut1_last_name
co_aut1_first_name
co_aut1_institution
co_aut1_city
co_aut1_country
co_aut2_last_name
co_aut2_first_name
co_aut2_institution
co_aut2_city
co_aut2_country

Anyone?

HUH??? I thought you were trying to count co-authors??

By the way, if you ARE intending to count co-authors. You need not even put them in an array since it appears from your output that each co-author is represented by a single record.

//increment a counter...
while ($row = mysql_fetch_array($result)) {
	// Display your rows.
	$co_authors++;
}
//or even easier, just call this function from the same query result.
$co_authors = mysql_numrows($result);
