PHP - Read A Text Area Without Submitting
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. 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>
Imagine a form with 2 textboxes and one button. I need to check value of these texboxes and if they are not empty to send typed data into some php file. Otherwise to give user warning message that please enter the text in textboxes. I am sure it is very simple issue. I need to check the value of the textboxes inside the same php file where textboxes are located. 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>'; ?> This topic has been moved to JavaScript Help. http://www.phpfreaks.com/forums/index.php?topic=318486.0 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> Note that my code still use the old mysql query and I am aware of that. I want to migrate it to mysqli soon but it will have to wait until I learn how to do so. Meanwhile, please help me with the code that I have now. Thank you
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 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 have a text box on page 1 that has a unique changing value using
$Comment_Name = dechex(time()); $_SESSION['COMMENT_NAME'] = $Comment_Name; // Lines 42/43
Comment As the name of the text box is stored in a session variable then it should be a simple mater of retrieving the value on page 2. /****************************/ $CommentID = $_SESSION['COMMENT_NAME']; if($direction == "Add record") { $Comment_Name = $_SESSION['COMMENT_NAME']; $_SESSION['DE_MyReason'] = $_POST['Reason']; // Keep the default regardless $_SESSION['DE_Money_In'] = $_POST['MoneyIn']; $_SESSION['DE_Money_Out'] = $_POST['MoneyOut']; $_SESSION["DE_DD_Entry"] = $_POST['DD_Entry']; $_SESSION["DE_MM_Entry"] = $_POST['MM_Entry'];
$_SESSION["DE_Comment"] = $_POST[$CommentID]; /* This should retreve the posted value */

It works fine however when I submit something it says that I havn't supplied all the fields. I have spent quite a while trying to figure this one out but I am very new to php and understand that it's probably a missing comma or something! 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 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">' . $errors['body'] . '</span>'; } ?> </li> What seems to be the problem?! Debbie Hi, I'm not sure if this should be in PHP or HTML so apologies if it's in the wrong area. I have a form with a text area element but when the text is submitted, tags such as <br> aren't included so the outputted text is never formatted correctly such as there being no paragraphs. Is there a way make sure such tags are included in the output text? Ta. Hi, Im trying to make a script to mass update a load of links in my database but im stuck on the basics, How can i detect a new line in a text area? Anyone know why this dosen't work? Code: [Select] <?php if($_POST[newlinks]) { $newlinks = preg_split("\n", ($_POST['newlinks'])); $i = 1; foreach ($newlinks as $newlink) { echo "$i - $newlink <br />"; $i++; } } else { echo "<form method=\"POST\" action=\"changehost.php\">"; echo "<br /> <strong>Enter the new links to try and replace old ones</strong> <br />"; echo "<textarea rows=\"16\" name=\"newlinks\" cols=\"84\"></textarea>"; echo "<input type=\"submit\" value=\"Submit\" name=\"B1\">"; ?> Hey, I'm looking for some PHP code which can read a certain text file i have.

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.
