I am trying to pass a variable frm php to a javascript function, however a space keeps getting appeneded, and I can not see how.
The relevant php code snippet:
<p>Click for full description </p>".$brand."
<p>DELETE
$brand is what I want to pass, and deleteRec is the name of the function.
At the end of the first line I am echoing out brand before the link to deleteRec, and it contains no space. In my test case, it is set to simply 'o'.
The link that is genereated for deleteRec however, clearly contains a space, and I don't know where it is coming from.
DELETE
Do var_dump($brand) and look closely - there's almost certainly a space in it!
In which case, you can guard against it with trim
$brand=trim($brand);
Change:
<p>DELETE
to:
<p>DELETE
and tell us how it goes.
Try do echo the following:
echo "--$brand--";
This way you'll be able to see if there are any spaces in the variable.
As a general matter of style, I would change second link from:
<a href=\"#\" onclick=\"
deleteRec('".$ARTICLE_NO."', '".$brand."', '".$pg."', '".$nextArticleNo."')\">DELETE</a>
to:
<?php
$deleteRecArgs = "'$ARTICLE_NO', '$brand', '$pg', '$nextArticleNo'";
?>
DELETE
It's easier to read and maintain.

pretty new to Mysql, HTML and PHP and I can't seem to find much information on this trouble i'm having.
I Am making my own rough project manager type thing and I have a form that lets me change the contents of each individual change log, the problem I have however is that when I load the data in to the text area it start with a big indentation at the start, like 3-4 tabs inwards. I would attach an image but I need at least 10 rep to do that.
Basically, it feels like the data in the database has tabs or something at the start of it, but when I go to look in PHPmyadmin at the field, it just looks like it should do, not tabbed at all.
I've tried using strip_tags() but I think it only works on visible tags.
Does any1 know how to get rid of this or what is causing the problem?
I'll be following this question closely to see if anybody can provide an answer because I'm stumped.
Thanks,
Try to echo your php code with no blanks :
Possible tabs, bad example :
<textarea>
<?php echo $tabContent; ?>
</textarea>
Avoiding tabs :
<textarea><?php echo $tabContent; ?></textarea>
You can also try to trim your php content like that :
<textarea><?php echo trim($tabContent); ?></textarea>
Try doing var_dump and look how long your queried string is.
If it is as long as in your database you problem is within the textarea.
Is there any css you use with textarea?
I'm quite new here. I'm trying to make a blog/journal site that allows users to post their own journal. I'm still quite reluctant on making it because I am really afraid of malicious code injections.
So here's a sample code:
<?php
$test = "<b>blah</b>"; //User input from SQL
echo "$test";
?>
What will come out is just the word "blah" in bold right? What I was trying to achieve was to echo "<b>blah</b>" instead. I don't want people to put some PHP codes that can actually mess up my whole web page. Please keep in mind that the variable $test is actually a MYSQL query, so that variable will be needed as an example. I know you can do echo '$test'; but it just comes out as "$test" instead. I feel like pulling my hair out I can't figure it out yet.
The second solution I know of is the htmlspecialchars(); function, but I want the strings to display as what I typed, not the converted ones...
Is there any way I can do that?
I think the OP wants the HTML itself to be output to the page, and not have the tags stripped. To achieve this, you can run the string first through htmlentities()
$test = '<b>blah</b>';
echo htmlentities($test);
This will output:
<b>blah</b>
Which will render in the page as
<b>blah</b>
Echo don't execute PHP code from string. This is impossible and this is not security hole in your code.
You can use a template engine like Twig for exemple.
If htmlspecialchars(); is not the one you are looking for, try the header() option.
header('Content-type: text/plain');
When you are gonna give <b>Hi</b> to a browser, it will be displayed in Bold and not the text be returned. But you can try this way, outputting it inside a <textarea></textarea>.
Or the other way is to use htmlentities():
<?php
$test = "<b>blah</b>"; //User input from SQL
echo htmlentities("$test");
?>
So I'm trying to do something extremely simple, and after reading through forums, and researching on google I still can't figure out why this is not working. But this is mostly like because I'm still a very much noobie programmer. I'm trying to send information through a url, and having a script pick it up using the $_GET super global.
Here's the link code, in a file called TESTFORM.php:
<p>
Here's a link:
ID
</p>
This is the TESTGET.php script:
<?php
if (isset($_GET['id']))
echo 'it is set<br />';
else
echo 'it is not set<br />';
?>
This yields in a "It is not set" appearing on the page every time. Any thoughts? Are there ghosts in my computer ruining my code? Thanks for taking the time to read through this! Happy coding!
I'm no PHP programmer, but I do know from HTML that computers (especially file names) don't "like" spaces. Try removing the spaces in the id = 5 code.
Your problem is the extraneous space here around the URL parameters:
ID
That will result in PHP seeing the parameter as $_GET["id_"]. The space gets converted into an underscore.
It's always best to use var_dump($_GET); or var_dump($_REQUEST) when you run into such problems. Secondarily it is sometimes helpful to get rid of isset in such cases. Albeit you have a custom error message in place of the language notices intended just for that.
Have you tried to remove spaces in your link?
ID
Code seems fine at a glance, have you tried removing the spaces in
?id = 5 to ?id=5
I am developing a Facebook App in which I get some text from the Database and Display it on the Page.
The Problem is that I want to insert a line Break in the variable e-g
If I copy a Text from database and store it in a Variable..
Let say
$text="I love to walk";
I want to insert a line break after "to" how can i do that?
I had tried to store the text like this in html
"I love to <html> <br> </html> but that didn't worked..
Just suppose this is the Text ..may be next time the text is entirely Differnet having no "to" word.
Depends on if you want to create new line in code output, or in HTML
$nl = "\r\n";
$nl_html = "<br />";
That exmple you provided modify like this:
$lyrics = "I love to <br> but that didn't worked.."
To automatically add line break after some text, use preg_replace
$lyrics = preg_replace('/to /',"to<br />",$lyrics);
see http://php.net/manual/en/function.preg-replace.php
$new_str = str_replace('to', 'to <br />', $str, 1);
If you want to output the text in a html page, you need to make it
$text="I love to <br /> walk";
If you want to output it to a file you need to make it
$text="I love to\r\nwalk";
or
$text="I love to\rwalk"; depending on the OS on which you will be reading the file
Hi I was having issues with this just as you do earlier today (I am new to PHP).
The way I fixed this was as follows:
$format_text = nl2br($formatthis);
You would then refer to $format_text.
What it does is it keeps the line breaks.
However I am not quite sure what you mean with your OP, after re-reading it. I went by the topic and I answered it as best I could.
If you are having trouble let's say echoing html code then most definitely you are having trouble with escaping characters.
For instance:
echo "a href="something" /a this won't work.
echo "a href=\"something\" /a this will work, notice the .
you have two options either use preg_replace or use a variable to save the value
please see php documentation for further info
I'm trying to experiment with taking text from a textarea in a flex project and open it up in a php page. But the php isn't line breaking where it should be...
an Example of the text i'd like to bring over to php would be:
You: Hi there
Them: Hello
You: This is a great example
Them: I know right?
Here's my php:
<?php
$text= $_GET['text'];
echo $text;
?>
Right now I came up with something like this in the actionscript...
var chatBox:String=chat_box.text;
navigateToURL(new URLRequest("savelog.php?text="+chatBox), '_blank');
I also tried something like:
var chatBox:String=chat_box.text.valueOf().replace("\n","<br/>");
and
var chatBox:String=chat_box.text.toString().valueOf().replace("\n","<br/>");
But apparently the \n isn't translating over no matter how I get the chatBox var so its not even making a <br/>
But, even if i did get that to work it wouldnt be ideal. Because eventually in the end I want to be able to just incorporate the pastebin API to paste this GET data and post it on there. And I don't think it would look too pretty with having <br/> after every line...
So my questions is, is it possible to bring this text over to php and recognize the line breaks in a way that would work well with what im eventually trying to accomplish?
edit:
I'm a little confused because var chatBox:String=chat_box.text.toString() actually returns the text with \n at every line break and i can see the \n on a trace statement...but when im looking in the URL text there is no \n anywhere...any ideas? because if the \n would appear the ln2br() solution might work
Take a look at ln2br() its a built in function in PHP. It also handle more than jsut the \n might be usefull in your case and i dont see that your using it yet! Try it out and let me know! You also might want to check out any encoding issues.
