PHP - Help Detecting Empty Lines In A Text Area
Hey guy, I really need your help with this.
I have Input from a text area, in this format: a b c d e f g 12 34 435 124 What I need do to is to output only a certain line from every block of text, every block is divided by one or more empty lines. I have done this: $input = $_POST["input"]; $lines = explode("\r",$input); $num = count($lines); $line_to_extract = $_POST['line_to_extract']; for($i=0;$i<$num;$i++) { if($i == $line_to_extract) { echo 'Line '.$i.': '.$lines[$i].'<br />'; } } What I need to do is to detect the empty line so I can keep track of the line to extract. PLEASE HELP!!! Similar TutorialsI'd like to use a text editor like this one: http://tinymce.moxiecode.com/examples/full.php for my forums. But I am not sure exactly how I would prevent abuse and injects to messed up the page, rather than being contained in the designated area it is meant for. Could some one please help me, I know htmlspecailchars will not work, since some of the code needs to render as html I’m trying to construct a button that simply writes an "aleph" character into a text area, see below.
My code does not work, can anyone tell me why ? How should I fix it ?
<!DOCTYPE html>
<html>
<meta charset="UTF-8">
<head>
<title>Example</title>
<script type="text/javascript">
//JavaScript code goes here
function insertAtEnd(text)
{
var theArea = document.getElementById("thisArea");
theArea.value += '' + text + '';;
}
</script>
</head>
<body>
<input type="button" id="aleph" name="aleph" value="Write an aleph"
onClick="javascript:insertAtEnd(\'<span>א</span>\');return(false)" />
<textarea id="thisArea"> </textarea>
</body>
</html>
I need to read all the rows from a text file between two specific lines into an array where I can process them. I then need to do the same thing again until the end of the file. The file is too large to read the entire file into an array. The number of rows that are between the key lines are variable. This is what I have so far to read the first set of rows into the array but it is only reading the first row when in fact in this case there are 15. Any pointers as to where I am going wrong please?
if ($_POST['srch']=="Import") {
//open file for reading
$family_rec=[];
$file_handle = fopen($fn, "r");
if(!$file_handle){echo "Could not open file";}
while(!feof($file_handle)) {
$line = fgets($file_handle);
if ((strpos($line, "0 @") !== false) && (strpos($line, "FAM") !== false)) {
$famref = explode("@", $line);
$line = fgets($file_handle);
//echo $line."<br>";
do{
$family_rec[]=$line;
$line = fgets($file_handle);
//echo $line."<br>";
}
while((strpos($line, "0 @") !== false) && (strpos($line, "FAM") !== false));
print_r($family_rec);
}//end of family
}//end of while not eof
}//end of import
I have a .txt file containing hundreds of lines of Names (e.g. Brad, Jennifer, etc.) What coding can I use to only echo the first 20? Hi All, If someone types in my textarea without any hard returns, it echos the entire text on a single line, which expands my site very very far and screws up the layout. how can I echo the text but limit the number of characters per line before I insert my own line break? The code is just: Code: [Select] echo $message; I have a form that is processed using PHP (post method) and there is a textarea people will enter text into. After processing, the text is displayed to the user. However, if the user did a Carriage Return (i.e. hit Enter) when they originally entered the text, that text does NOT show on a new line when displayed later. For example, if they type this into the text area... "Hello there (they hit Enter here) How are you (they hit Enter here) Good I hope" It will display like this, all on one line: "Hello there How are you Good I hope" In other words, it doesn't seem to remember that Enter was hit. Is there some way to "preserve" the fact that someone hit the "Enter" key, so that when text is displayed later, it will show the text on a new line if the user in fact hit "Enter" when originally typing it. I am probably not using the right terms in the right spots (i.e. newline, carriage return, enter, etc) but I think you get the picture Let me know if anyone knows how to do this. Thanks! I want to add a text area to this so when an Administrator of the site clicks the refusal button, they will be able to type in a reason for the refusal. Code: [Select] <?php echo '<a href="adminDeleteGoodie.php?delete_id=' . $delete_s_find . '" onClick="return confirm(\'Are you sure you want to delete ' . $makesure_s . ' from the Goodies Approval List? If so, please leave a reason for the upload being denied. NEED A TEXT AREA RIGHT HERE \');"><img src="images_new/remove.jpg" border="0" /></a>'; ?> Extremely new here and to PHP and I have exhausted my newbie resources and my brain on this one. Concept: Cron Job to INSERT 5 lines per hour (Not the whole list at once) Script to read a pipe delimited text file (about 5k Lines) Open File Get last (bottom) 5 lines of file, ignore the rest Insert those 5 lines into my database Open File, Remove last (bottom) 5 lines I am able to do parts 1-3 but not part 4 (removing last 5 lines) Please help me! Code: [Select] $data = array_slice(file('data.txt'), -5); foreach($data as $value) { $fields=explode("|",$value); $num=count($fields); for ($n=0;$n<$num;$n++) { $null=""; print ($n==0) ? "Importing Video...<BR>" : $null; } // Insert into tmpvideos table here include("includes/config.php"); $last_id_result = @mysql_query( @"SELECT ext_id FROM tmpvideos ORDER BY ext_id+0 DESC, id DESC" ); if ( 0 < @mysql_num_rows( $last_id_result ) ) { $last_id = @mysql_result( $last_id_result, 0, "ext_id" ) + 1; } else { $last_id = "1"; } copy($fields[3], "thumbs/ex_".$last_id.".jpg" ); $fields[3] = "thumbs/ex_".$last_id.".jpg"; set_time_limit(0); mysql_query("INSERT into tmpvideos (id, ext_id, title, description, duration, category, date_added, thumb, video, views, rating, votes, status) VALUES ('','".$last_id."','$fields[0]','$fields[1]','$fields[5]','$fields[6]',NOW(),'$fields[3]','$fields[2]','','','','1')"); } I understand the 'concept' but am unable to grasp the code!

I've looked around the internet to find how to do this and I found two methods:
htmlspecialchars();
and
mysql_real_escape_string();
I wrapped my text into one of the two function in order to pass in text with apostrophe in it to the database.
However I encountered a problem.
With mysql_real_escape_string, I got the desired effect that I want but the problem is that, the function also apply its effect onto html img tag. So <img src="test"> turns into <img src=/"test/"> and therefore images (and also links) will not appear.
With htmlspecialchars, again I got the desired function that I want which is to pass in apostrophe into the database. The problem with this is that when I pull the data out from the database and echo it onto my page, it doesn't render and show as a plain html code.
What confuse me a lot is that, it works fine inside my localhost.
Please help
Thank you!

4 downloads How can I make this textarea box height larger? The width is fine but I need to make it a little taller so I don't have to scroll to see what I've typed in. Thanks Code: [Select] <tr> <td colspan="4"><b>Notes:</b> <textarea style= "width: 100%"> </textarea> </td> </tr> Hi, I've been asked to modify a section on a site for a local club. Basically, I've been asked to improve the name input section (a user may have to input up 15 names in one visit to the site). At the moment the site works like this: The user enters one members first name in one form box, then the surname in another, then presses "add name" which adds it to the list. What i want to be able to do (and i'm sure i've seen it somewhere), is have the user enter the list of names into one big text area: Type in the first name then the surname, hit enter for a new line in the text area then type the next name....etc. When the list is complete press "add names" button. Is there a name for this type of input? And does it work on the following principle: 1. The entire text sent from the text area can be exploded into an array using the line break as the delimiter 2. Each value in the array is then the first name and second name. 3. I can then explode each value further now using the space as the delimiter. 4. I am left with a bunch of arrays containing the first name in one value and the surname in the second Any help or pointers here would be class Cheers, John I want a Text Area on my form where I can enter the body of an article. It should be sticky so the input is not lost if there are form issues and the form has to be re-loaded. The problem is that when I type "mmm" into this field, after I click "Submit" my form is reloaded - because I didn't complete it - and several blank lines appear before and after the text "mmm"?! Here is my code... Code: [Select] <!-- Body --> <li> <label for="body"><span class="required">*</span>Body:</label> <textarea id="body" name="body" class="text" cols="20" rows="5" wrap="soft"> <?php if(isset($body)){echo htmlentities($body, ENT_QUOTES);} ?> </textarea> <?php if (!empty($errors['body'])){ echo '<span class="error">' . $errors['body'] . '</span>'; } ?> </li> What seems to be the problem?! Debbie I'm trying to retrieve the text from a text area and put this in a PHP variable without submitting the form. The text is provided by a database and I want to format it for the user. How can I do this with PHP? So basically: Code: [Select] <form id="createForm" name="createForm" method="post" action=""> <textarea name="subjectTextArea" id="subjectTextArea" cols="45" rows="5"> This is the text I want to put in a PHP variable before the form is submitted. </textarea> </form> <?php $txtArea = ? ?> Thanks for the help. Hi! I have a text area on my webpage which takes in user php scripts and produces an output in an adjacent window. I am trying to find out how I can auto include some php tags into the input text area so that the user doesn't have to keep typing them in every time. Code: [Select] <form name="form1" method="post" ACTION="editor.php"> <textarea rows="10" cols="60" id="code" name="code"></textarea> <span class="submitbutton">Test code</span> </form> Thanks in advance, Jay Hi, I'm not sure if this should be in PHP or HTML so apologies if it's in the wrong area. I have a form with a text area element but when the text is submitted, tags such as <br> aren't included so the outputted text is never formatted correctly such as there being no paragraphs. Is there a way make sure such tags are included in the output text? Ta. Hi, Im trying to make a script to mass update a load of links in my database but im stuck on the basics, How can i detect a new line in a text area? Anyone know why this dosen't work?
