at least 7 words separated by commas?

[jamiet757]

I am trying to figure out how to tell if what a user enters in a textbox is at least 7 words, separated by commas. It can be 100 words, I don't care, as long as it is at least 7. It will appear like this:

 

word1,word2,word3,word4,word5,word6,word7

 

or

 

word1, word2, word3, word4, word5, word6, word7 (with spaces)

 

Anyone have a statement that I can use?

 

Coincidentally, I need to check to see if there is at least 7 words in a sentence as well, i.e.:

 

The quick brown fox jumped over the.

 

It could be 100 words again, but it needs to be a minimum of 7.

 

Any help is appreciated!

How accurate do you need to be, the simplest solution would probably be to use...

 

substr_count( $string, ',');
// or 
substr_count( $string, ' ');

It is just to make sure someone has entered at least 7 keywords and a description of at least 7 words, to prevent things like "A photo." that give no meaning to the description.

The previous code will work, but can be tricked with '      ' or ',,,,,,,,'. A better solution could be created with Regex if needed. Something like this to check for comma separated.

 

'#([^,]+,){7,}#i'

 

...and for the spaces...

 

'#([^ ]+ ){7,}#i'

Great thanks!

Just thought, that will require the pattern ending with a comma, try this instead...

 

'#([^,]+,){7,}.*#i'

 

...still may not be perfect, haven't tested it or anything.
