Hi,

I have a code which helps me to edit a text and save it to database.

the files I have:

articles.html

PHP Code:


			
<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=windows-1256">

<script type="text/javascript" src="prototype.js"></script>



<script type="text/javascript">



    function init()

    {

        Event.observe("edit", "click", function(e){ edit_in_place() });



        Event.observe("save", "click", function(e){ save() });



        Event.observe("cancel", "click", function(e){ cancel() });

    }



    function edit_in_place()

    {

        $("save_settings").style.display = "inline";



        $("edit_settings").style.display = "none";



        var article_title = '<input type="text" name="article_title" id="article_title"';

        article_title += 'size="30" value="'+$("title").innerHTML+'" >';

        

        $("title").innerHTML = article_title;

        





    }

    

    function save()

    {

        new Ajax.Request("articles.php", 

            {

                method: "post",

                postBody: "title="+$F("article_title")+

                "&uid=1"+"&save="+$F("save"),

                onComplete: show 

            }

        );

    }



    function show(res)

    {

        $("title").innerHTML = $("article_title").value;

        $("save_settings").style.display = "none";

        $("edit_settings").style.display = "inline";

    }



    function cancel()

    {

        $("title").innerHTML = "Edit the article title here...";

        $("save_settings").style.display = "none";

        $("edit_settings").style.display = "inline";

    }



</script>



</head>



<body onload="init()">

    <div>Title:</div>

    <span id="title">

        Edit the article title here...

    </span>

    

    <span id="edit_settings">

        <input type="button" id="edit" name="edit" value="edit" >        

    </span>

    

    <span id="save_settings" style="display:none">

        <input type="button" id="save" name="save" value="save">&nbsp;

        <input type="button" id="cancel" name="cancel" value="cancel">

    </span>

</body>



</html>

prototype.js

and articles.php which conatin the orders to save the text in the database.

the problem is I don't want any body to enter html code,

I mean if some one edit the text and write:

<b>test</b>

it should give him this:
<b>test</b>

and NOT:
test

so how to do that?

Thanks MoT3rror,

but this is for the php file.

I need it for the javascript!

--------------- Added [DATE]1214975648[/DATE] at [TIME]1214975648[/TIME] ---------------

ok I know I should use escapeHTML()

but how to add that to this code?

Code:

<script type="text/javascript"> 

    function init() 
    { 
        Event.observe("edit", "click", function(e){ edit_in_place() }); 

        Event.observe("save", "click", function(e){ save() }); 

        Event.observe("cancel", "click", function(e){ cancel() }); 
    } 

    function edit_in_place() 
    { 
        $("save_settings").style.display = "inline"; 

        $("edit_settings").style.display = "none"; 

        var article_title = '<input type="text" name="article_title" id="article_title"'; 
        article_title += 'size="30" value="'+$("title").innerHTML+'" >'; 
         
        $("title").innerHTML = article_title; 
         


    } 
     
    function save() 
    { 
        new Ajax.Request("articles.php",  
            { 
                method: "post", 
                postBody: "title="+$F("article_title")+ 
                "&uid=1"+"&save="+$F("save"), 
                onComplete: show  
            } 
        ); 
    } 

    function show(res) 
    { 
        $("title").innerHTML = $("article_title").value; 
        $("save_settings").style.display = "none"; 
        $("edit_settings").style.display = "inline"; 
    } 

    function cancel() 
    { 
        $("title").innerHTML = "Edit the article title here..."; 
        $("save_settings").style.display = "none"; 
        $("edit_settings").style.display = "inline"; 
    } 

</script>

You should ALWAYS sanitize data server-side. That means, you should run htmlspecialchars() in your PHP script. Sanitizing client-side (ie. with Javascript) can be easily bypassed.
