I have html data like text including image src.when I alert using jquery it works fine. Entire html is displayed in alert box.And then I want to send that entire html data and text and something's id using query string of JQuery like:
$.post('something.php','socialprofileid='+socialprofileid+
'&txtMsg='+msg+'&postedHtmlMsg='+HtmlMsgresult)
But I need that entire html data including text and id in php page like get html data, text, id in JQuery alert box
I try to use window.btoa function(base64 encoded format) for HtmlMsgresult. After doing base64 encoded format in javascript, when I try to send in php page, it doesn't get any print in php page.
Another thing is there any solution Text and htmldata(html text and img src) are combined and then it is done the base64 encode.And then it is send in php page using query string like:
if(txtmsg='') {
var result=window.btoa(htmldata);
} else {
var content=text+htmldata;
var result=window.btoa(content);
}
$.post('something.php','socialprofileid='+socialprofileid+'&result='+result)
Is it possible to do that?
And then I want to insert into database in something.php and then in another page I want to fetch the htmldata and text which are encoded by base64 using jquery. Then it is converted by base64_decode function.
But within text and htmldata, How to extract text , htmltext, htmlimgsrc differently from the database table.
If u know about these type of problems, please reply me
I need your hand
Thank you
$.post('something.php',
{socialprofileid:socialprofileid,
txtMsg:msg,
postedHtmlMsg:HtmlMsgresult});
jQuery will apply encodeURIComponent by itself. And yes, you need encodeURIComponent applied to the values of the parameters if you want to encode the data by yourself. Read the following topic When are you supposed to use escape instead of encodeURI / encodeURIComponent?
ps: you do not have to do anything in the php script, the data will be decoded automatically by the server. Access $_POST['socialprofileid'], $_POST['txtMsg'] and so on in php.
In php, you can get the post parameters with the $_POST variable.
<?
echo $_POST['socialprofileid'], PHP_EOL;
echo $_POST['txtMsg'], PHP_EOL;
echo $_POST['postedHtmlMsg'], PHP_EOL;
?>

I ran into an issue recently. I have a system where users can post stuff. One of the fields is the title field. So to save user input safely I use htmlspecialchars on the user submitted title and send it to a function that then saves to the database (after using mysql_real_escape)
Now on the client's side I use json get to fetch this title
$.getJSON("PHPFILE", function(json) {
// let's say json.title is the title we need so...
var title = json.title;
}
Now the thing is this user given title value can contain anything, even html tags (for reference let's say it now contains
<script>alert('');</script>Some Text!
so since I use jquery I thought of clearing those using the .text() function
var cleanTitle = $(title).text();
alert(cleanTitle);
However this immediately throws an error. In chrome it says
Uncaught Error: Syntax error, unrecognized expression ...
So I verified if this title variable is a string. And it is indeed a string. (Btw for some reason if this variable contains only numbers there is no error)
Using the following however gives me the text but the tags aren't removed
var cleanTitle = $.parseHTML(title);
cleanTitle = $(cleanTitle).text();
alert(cleanTitle);
This outputs
<script>alert('')</script>Some Text!
How can I remove all html tags? Any suggestions? I am planning to use this title text to set Browser title. Thanks.
document.title = $('<div />').append( $('<div />').html( title ).text() ).text();
Appending the string twice should fix the htmlentities issues.
Since you are using MySQL as engine to store that kind of data, you are clearly using PHP scripting. Suggestion: use PHP's strip_tag() and you are cutting "workload" for jQuery/Javascript by letting PHP do the work.
I am using a jquery editor.And the content will be saved in the database along with the html tags . That is for example I have typed "aneesh" in the editor and using editor makes the text bold and italics the saved the content to db .
So the content will be saved in the db along with text and html tags
Now i want take the content from db and want show the text in formated ways that is need to transform the html tags that in my the content want to show like this aneesh Is there any way for this please help me
To store and retrieve html you should use htmlspecialchars() - this preserves html tags etc etc when saving and htmlspecialchars_decode() - this converts them back to proper html that can be displayed - when displaying the retrieved content.
Storing using this and calling the decode function when populating the textarea behind the wysiwig editor will/should have kept everything preserved.
Or you can also use htmlspecialchars()
$a=htmlspecialchars($a);
<text>$a</text>
wud help u save and retrieve the html characters
Just select the data out of database (i'm using PDO): and echo/post the result to the document without string formating:
$sql = 'SELECT * FROM table;';
$stmt = $DB->prepare($sql);
$stmt->execute();
$row = $stmt->fetch(PDO::FETCH_ASSOC);
echo $row['result'];
if you have content with html tags like i-e <b>Hello</b> in the database, and when you return it from the database again, the jquery editor that you are using will automatically remove those tags and will transform your text again and make it i-e bold (if hello in case).
There is no need to do anything but just echo it out.
you need to use javascript for better and easy solution.
get raw html content from db (with php) to show web browser (with javascript): innerHTML or .html() (JQuery)
I want to send a set of HTML contents using POST method in Ajax. It consists of some special characters When I retreive it using PHP, only half of the content is there.
This the example content which is used to post to the other Page. This post operation is performed by using the jQuery .post method.
Passed Content (via JS):
<div><label id="aboutDescription" style="">Firstline</label> </div>
<div><label id="about" style="">Secondline</label></div>
Retrieved Content (in PHP):
<div><label id="aboutDescription" style="">Firstline</label>
When I get using the $_REQUEST method I received only half of the contents.
I found the problem that whenever I get the " " or any other special characters the contents gets terminated. So I think I have to encode the content from javascript and decode the same content in PHP.
If I use encodeURIComponent in Javascript, how should I decode the contents in PHP?
Is there any alternate functions which is equal to decodeURIComponent(Javascript Function) in PHP?
To decode the content using PHP, use this :
$decoded_string = urldecode('put encoded string here');
The following jQuery ajax function runs a PHP script that queries a MySQL database containing entries that are encoded as UTF-8:
function searchLocations() {
var stateSelected = $("#stateSelect").val();
$.ajax({
url: 'ajax/json.php',
dataType: 'json',
data: 'state='+stateSelected,
success: function(data) {
placeMarkers(data.markerdata.markers);
}
});
}
The JSON object returned to the function contains the longitudes and latitudes of map marker objects as well as a name to display in an info window when each marker is clicked.
Every name loads fine, and is displayed without a problem except for a single name which contains the character "ñ". This name is returned in the JSON object as "null". How can I make this name display properly?
I used to have this problem and I found there was two options:
In PHP convert all characters into HTML friendly characters using the PHP function htmlentities (http://php.net/manual/en/function.htmlentities.php) before returning it to the jQuery function.
If that fails or the characters are not converted you could try using base64 encode and decode. In PHP you can encode the data using base64_encode function (http://php.net/manual/en/function.base64-encode.php). Then in jQuery you could use one of many base64 encode and decode plugins to decode the data. I have used this plugin successfully in the past: http://plugins.jquery.com/project/base64-encode-and-decode
Failing both those options it may be worth looking at the character set used by your page. Try and use UTF-8 to encode your HTML and see if that helps.
Without using jQuery and AJAX if you did a basic PHP page that queried the data in question and prints the name out does it still not display correctly. If it doesn't it could also be a character set issue with MySQL.
Hope any of these pointers help. Let me know how you get on.
I have a php page that is returning some data in json. Basically I am doing echo on this page.
The data being returned has some html tags. This is causing my jQuery code to break.
Is there a way to clean up the data and strip off the tags before putting it in the json object?
Furthermore, I am trying to display the data from json into a textarea and ideally I would like to show the html tags in the textarea...
When you create the json, you can use json_encode() on the values that have html in your php code - this will escape the values in json so that it validates and will be usable in jquery. I haven't tried it, but you should not have a problem adding the value to a textarea.
