[SOLVED] Textarea

[14862875]

How do i limit the amount of words entered into a textarea to 100 words?

 

<form name='cloud_constructor' method='post' action='index.php'>

<table cellspacing='10px'>
<tr><td style="vertical-align:top;color:white;font-family:tahoma;font-size:12;">Please enter some text and click submit to create a cloud: </td><td><textarea name='text' rows='10' cols='30'></textarea>

</table>
<input type="hidden" name="submitted" value="TRUE"/>
<input type='submit' value='Submit'/>
</form>

I think you need JavaScript.

 

Give your form an onsubmit attribute such as -

<form name='cloud_constructor' method='post' action='index.php' onsubmit='return validate(this);'>

<table cellspacing='10px'>
<tr><td style="vertical-align:top;color:white;font-family:tahoma;font-size:12;">Please enter some text and click submit to create a cloud: </td><td><textarea name='text' rows='10' cols='30'></textarea>

</table>
<input type="hidden" name="submitted" value="TRUE"/>
<input type='submit' value='Submit'/>
</form>

 

Then with the validate function, you can check the length.

<script type="text/javascript">
function validate (frm) {
     return frm.text.value.split(' ').length <= 100;
}
</script>

 

In that JavaScript function, it checked if the word length inside the textarea is less than or equal to 100. It returns a boolean value. So if the textarea has more than 100 words, it returns false and the form is not submitted.

 

Hope this helps.

Make sure that you also check the string length on the server side of things as well as users can easily disable JavaScript and thus, render your little block useless.

 

if(strlen(trim($_POST['message'])) > 100){
//show error or whatever
{

[mrMarcus]

then use strlen to verify the length of the textarea for anybody who has javascript turned off, ie.

<?php
if (strlen($_POST['text']) > 100)
{
     //do something;
}
?>

 

man, you beat me to it .. posting it anyways

counting words, not strlen... right?

$words = count(explode(" ", $_POST['text']));
if($words > 100){
//fail code
}else {

//other code

just a thought

[waynew]

What if the user enters a word that is 4000 characters long? They'll surely break the entire Internet. Btw, yes I did notice that my code would cough up an error. But that was only put there to fool you guys into thinking that I wasn't perfect.

[mrMarcus]

man, i should read a little more carefully .. it's a word limit you want...

<?php
//turn into array;
$words = explode (' ', $_POST['text']);
//can lose the last word .. especially effective if also using a character allowance;
$discard = array_pop ($words);
// how many words are allowed in description output;
$word_limit = 100;
// reassemble text;
$words = implode (' ', array_slice($words, 0, $word_limit));
?>

 

try that;

Thanx guys helps a lot..slight problem

 

<?php 

if(isset($_POST['submitted']))
{

if(empty($_POST['text'])) OR ($_POST['text'])) <100
{
print "<span style='color:red;font-weight:bold;'>Please enter some text!!</span><p/>";
include('form.php');

}

else
{
$cloud_one=$_POST['text'];
$cloud_one=strtolower(stripslashes($cloud_one));
$cloud_one=count(explode(' ',$cloud_one));

if ($cloud_one<100){
print"You must enter atleast 100 words!";

}
else {print" Thanks for entering the required amount of words";

}

$cloud_one=str_replace('[^a-zA-Z ]+', '', $cloud_one);
$stopwords=array("a", "about", "above", "above", "across", "after", "afterwards", "again", "against", "all", "almost", "alone", "along", "already", "also","although","always","am","among", "amongst", "amoungst", "amount", "an", "and", "another", "any","anyhow","anyone","anything","anyway", "anywhere", "are", "around", "as", "at", "back","be","became", "because","become","becomes", "becoming", "been", "before", "beforehand", "behind", "being", "below", "beside", "besides", "between", "beyond", "bill", "both", "bottom","but", "by", "call", "can", "cannot", "cant", "co", "con", "could", "couldnt", "cry", "de", "describe", "detail", "do", "done", "down", "due", "during", "each", "eg", "eight", "either", "eleven","else", "elsewhere", "empty", "enough", "etc", "even", "ever", "every", "everyone", "everything", "everywhere", "except", "few", "fifteen", "fify", "fill", "find", "fire", "first", "five", "for", "former", "formerly", "forty", "found", "four", "from", "front", "full", "further", "get", "give", "go", "had", "has", "hasnt", "have", "he", "hence", "her", "here", "hereafter", "hereby", "herein", "hereupon", "hers", "herself", "him", "himself", "his", "how", "however", "hundred", "ie", "if", "in", "inc", "indeed", "interest", "into", "is", "it", "its", "itself", "keep", "last", "latter", "latterly", "least", "less", "ltd", "made", "many", "may", "me", "meanwhile", "might", "mill", "mine", "more", "moreover", "most", "mostly", "move", "much", "must", "my", "myself", "name", "namely", "neither", "never", "nevertheless", "next", "nine", "no", "nobody", "none", "noone", "nor", "not", "nothing", "now", "nowhere", "of", "off", "often", "on", "once", "one", "only", "onto", "or", "other", "others", "otherwise", "our", "ours", "ourselves", "out", "over", "own","part", "per", "perhaps", "please", "put", "rather", "re", "same", "see", "seem", "seemed", "seeming", "seems", "serious", "several", "she", "should", "show", "side", "since", "sincere", "six", "sixty", "so", "some", "somehow", "someone", "something", "sometime", "sometimes", "somewhere", "still", "such", "system", "take", "ten", "than", "that", "the", "their", "them", "themselves", "then", "thence", "there", "thereafter", "thereby", "therefore", "therein", "thereupon", "these", "they", "thickv", "thin", "third", "this", "those", "though", "three", "through", "throughout", "thru", "thus", "to", "together", "too", "top", "toward", "towards", "twelve", "twenty", "two", "un", "under", "until", "up", "upon", "us", "very", "via", "was", "we", "well", "were", "what", "whatever", "when", "whence", "whenever", "where", "whereafter", "whereas", "whereby", "wherein", "whereupon", "wherever", "whether", "which", "while", "whither", "who", "whoever", "whole", "whom", "whose", "why", "will", "with", "within", "without", "would", "yet", "you", "your", "yours", "yourself", "yourselves", "the"); 
$cloud_one=preg_replace('/\b('.implode("|",$stopwords).')\b/i', '', $cloud_one);


$wordCount = array_count_values($cloud_one);

print "<pre>";
	print_r($wordCount);
print "</pre>";


}
}

else
{
include('form.php');

} 

 

The count function clashes with the array_count_values function..how do i fix that

[mrMarcus]

why, what's the error?

 

and this line shouldn't be working :

if(empty($_POST['text'])) OR ($_POST['text'])) <100

 

assuming you had the <100 within the condition, what is it supposed to be doing anyways?  is what less than 100?  the string length?  the number of something?  you need to declare that.

 

besides that, having a check on whether the word count is less than 100 also checks if it is empty (assuming your value is returning 0, which is less than 100), making your (empty($_POST['text'])) unnecessary.
