Jquery get the id of clicked element and show hidden child div

Jquery get the id of clicked element and show hidden child div

i have an array of comments, and it should be possible to answer the comment.
<div>
<a href="#" class="answerBtn" id="<?=$comment->id ?>">Answer</a>
<div id="answerDiv" style="display:none;">
<form action="" method="POST">
<input type="hidden" value="<?=$comment->id ?>"/>
<p>
<label>Your name*</label>
<br />
<input type="text" name="answer_username"
id="answer_username" required />
</p>
<p>
<label>Your Email (optional)</label>
<br />
<input type="text" name="answer_email" />
</p>
<p>
<label>Your comment*</label>
<br />
<textarea name="answer_message" required></textarea>
</p>
<input type="hidden" value="<?=base_url()?>"
id="answer_baseurl"/>
<input type="submit" value="Send"/>
</form>
</div>
i want to display the form when clicking the link, but because each
comment has the same form i have to be specific, so i want to show the
form depending on the id of the comment. so i tried something like this
with jquery:
$('.answerBtn').click(function(){
var id = $(this).attr('id');
$('id + div').slideToggle();
});
but that doesn't really work...
can someone help me out?

C++ Main file does not display everything

C++ Main file does not display everything

My program read a *.txt file and prints a line from the file backwards. i
wanted to get the linenumber before it does so. after doing the loop, i
got my number, but everything after my "for loop" is not printing/
working. what is wrong with my code?
#include "oneLine.h"
#include <iostream>
#include <fstream>
using namespace std;
int main () {
OneLine aline;
ifstream testFile ("test.txt");
if (testFile.good()) {
int countLines = 0;
string temp;
for (int i = 0; getline(testFile, temp); i++)
countLines++;
cout << countLines;
aline.readLine(testFile);
aline.breakLine();
aline.printReverse();
//int a = aline.totalLines(testFile);
} else {
cout << "Error: Invalid File.";
}
return 0;
}

Access a database from a DialogFragment and toast a message

Access a database from a DialogFragment and toast a message

I have a DialogFragment which displays a simple yes/no question. When the
user presses "yes", I perform a database request (which basicaly deletes
an entry). I then toast a message to report a success or failure to the
user.
I try to avoid calling the database from the UI thread, so I created a
thread which will delete the entry, and from that thread I call a handler
in the DialogFragment to display the toast message.
My problem is that when the user presses the button, the thread is started
and the dialog is closed. As the thread is started, the data is deleted
from the database. But when I toast my message from the handler, the
DialogFragment is already detached from the parent Activity so I don't
have a context anymore to call Toast.makeText().
My question is how can I toast the message ?
I know I could create a Service to handle the database operation, but
wouldn't it be too much hassle ? Is there a simpler way ?
Thanks !

PHP/SQL Where, And, Order By -- works on one statement but getting an error on another similar query

PHP/SQL Where, And, Order By -- works on one statement but getting an
error on another similar query

I'm trying to add a section that shows if any year end awards are won by
an individual. I have any Champions and Reserve Champions showing just
fine. However, when I went to add the "year end awards" section I keep
getting this error:
You have an error in your SQL syntax; check the manual that corresponds to
your MySQL server version for the right syntax to use near 'show = yearend
ORDER BY year DESC' at line 1
I have played around with apostrphes, using a LIKE statement, removing the
ORDER BY, and anything I could think of but I am at a loss. I can't seem
to figure out what changed from the working statements that would cause an
error.
This works just fine
<?php
$id = $_GET['id']; //Gets the ID from the URL
$result = mysql_query("SELECT * FROM competition
WHERE id = $id
AND place = 'CH'
ORDER BY year DESC") or die(mysql_error());
while($row = mysql_fetch_array($result)){
echo $row['class'];
echo "<small>(";
echo $row['show'];
echo ")</small><br>";
}
?>


This does not work The only change I made in the below is place = is now
show =
<?php
$id = $_GET['id']; //Gets the ID from the URL
$result = mysql_query("SELECT * FROM competition
WHERE id = $id
AND show = 'yearend'
ORDER BY year DESC") or die(mysql_error());
while($row = mysql_fetch_array($result)){
echo $row['class'];
echo "<br>";
}
?>
