Hi,
How to solve no module named _tkinter problem
while running python program.
|
|
|
|
|
Lots of results for this error message on Google.
Look at this page under the section titled "Checking your Tkinter support". That might help.
http://wiki.python.org/moin/TkInter[^]

Hi,
accroding to that link document
"simply rerunning "make" should build the _tkinter extension."
Where to find the "make" i found in the python26 directory but,
i didn't found that "make" file from that directory.
|
|
|
|
|
Try renaming it to Tkinter, might work

I try to create contact form with captcha as security.
I found problem that when I submit form and I set that if it has any error go back to the input page
to correct.
When it goes back, the form is blank.
I want the form still remain what is in the textboxes or not reset data.
how can I do that?
I searched on Internet, it kinds of session_start() is problem
but when I deleted it, captcha is not work....
also, I try on delete captcha and test but still got the same result.
history.back(); then the previous page data is disappear.

You should redisplay the form, filling in the information that was entered.
|
|
|
|
|
I have already tried by use get method.
but it doesn't work.
header("Location:"."test2.php"."?name=$name&email=$email&message=$message&tel=$tel&country=$country&1=2");
in the input textbox did not show the values from _GET method correctly.
|
|
|
|
|
First, the register_globals option is now off by default and has been deprecated in PHP 5.3, so the line should be more like:
header('Location: test2.php?name=' . urlencode($_GET['name']) . ...
In PHP 5 there is a function for building the query string that does the hard work:
$args = array(
'name' => $_GET['name'],
'email' => $_GET['email'],
'message' => $_GET['message'],
'tel' => $_GET['tel'],
'country' => $_GET['country']
);
header('Location: test2.php?' . http_build_query($args));
The other thing to note is that you have to insert these values into the form:
<input type="text" name="name" value="<?php echo htmlentities($_GET['name']); ?>" />
|
|
|
|

I don't get it.
Ok、I will explain easily.
::::index.php::::
<form.....action ="save.php" method = "POST" ....>
</form>
::::save.php::::
if(check captcha is wrong)
{
echo......alert+history.back();
exit();
}
..............................
the code which u gave to me
I have no idea how to apply since my form use POST...
can I used both POST and GET??
|
|
|
|
|
Sorry, yes - you should use $_POST instead of $_GET for posted form data. The values on the form itself should use $_GET though, since they are passed back in the query string.
Here[^] is the relevant page from the PHP documentation.
|
|
|
|
|
To add memory to a page I use this pattern:
some_page.php
<?php
$uname = "":
if(isset($_POST['user_name']) && strlen($_POST['user_name'])>0))
{
$uname = htmlentities($_POST['user_name'],ENT_QUOTES);
}
echo "<form action='' method='post'>\n";
echo "<input type='text' name='user_name' value='".$uname."'>\n";
echo "<input type='submit' value='Save' name='action'>\n";
echo "</form>\n";
?>
This makes memory of the code easier. If the data being passed is not to much then you can use a $_GET instead of $_POST. Also the process logic can be moved into a separate script that you include to keep the main script here clean and readable. The echo'd form ends with a newline so you can view source in a browser for debug purposes.

Hello All,
Has anybody seen a BNF grammar for PHP?...preferably the 5.3.X?...some place you can point me to?

I am having a problem understand how to work with time zones in PHP
I am trying to create a function where i can pass it a time zone and it will calculate the time in that time zone.
i have read countless forms about this and still have hit a brick wall.
If any one has any links or information they can share on how to do this i would be forever grateful.
All i need to do is find out what the current time is in eastern pacific and central time zones.

This is a cut'n'paste from the DateTime::setTimezone section of the PHP manual:
Example #1 Setting and getting DateTimeZone objects
<?php
date_default_timezone_set('Europe/London');
$datetime = new DateTime('2008-08-03 12:35:23');
echo $datetime->getTimezone()->getName() . "\n";
$datetime = new DateTime('2008-08-03 12:35:23');
$la_time = new DateTimeZone('America/Los_Angeles');
$datetime->setTimezone($la_time);
echo $datetime->getTimezone()->getName();
?>
The above example will output:
Europe/London
America/Los_Angeles
Elsewhere in the date/time chapter there are heaps of examples of various date/time manipulations. What I think you want to do is something like this:
$datetime = new DateTime(something);
$datetime->setTimezone(xxx);
$timexxx = $datetime->format($formatstring);
$datetime->setTimezone(yyy);
$timeyyy = $datetime->format($formatstring);

Why? Any normal Linux distribution should alredy include the md5sum program.

Those headers are obsolete since the ISO standard for C++ was accepted in 1998. Fix the errors in the source or find a non-obsolete version of MD5 (if you really don't have md5sum on your system).

Is there anyway that when you make a selection in a drop down list that it will be implemented without the need to then click the submit button.
My problem is this I have 3 drop down lists, size, font and colour all work fine if you click the submit button showing the selected font in the colour and size, but the page then refreshes and resets the lists. So what I am trying to do is implement any one list without refreshing the page so that the other two boxes do not reset.
Example, if I select size, then a font, then the colour, but do not like the font, I would have to go through the whole process again from scratch, instead of being able to just go back and select another font. I don't think it matters if the submit button has to be clicked or whether just making the select would have its own submit function.
This is the test page

Any suggestions would be welcome

I'd initially thought you'd have to use ajax, though now I'm not so sure.
If you only want to use the fonts on the client machines, you could use something like this:
<html>
<head>
<script type="text/javascript">
function byId(e){return document.getElementById(e);}
function setFont()
{
var tgt;
tgt = byId("output");
tgt.innerHTML = byId("textInput").value;
tgt.style.fontFamily = byId("fontCombo").value;
tgt.style.fontSize = byId("sizeCombo").value;
tgt.style.color = byId("colCombo").value;
}
</script>
<style>
body { background-image: url(darkbg2.jpg);}
</style>
</head>
<body onLoad="setFont();">
<select id="colCombo" onChange="setFont();">
<option value="#000000">Black</option>
<option value="#FF0000">Red</option>
<option value="#00FF00">Green</option>
<option value="#0000FF">Blue</option>
<option value="#FFFFFF">White</option>
</select>
<select id="sizeCombo" onChange="setFont();">
<option value="5mm">5mm</option>
<option value="1cm">10mm</option>
<option value="15mm">15mm</option>
<option value="2cm">20mm</option>
<option value="1in">25mm</option>
<option value="3cm">30mm</option>
</select>
<select id="fontCombo" onChange="setFont();">
<option value="arial">Arial</option>
<option value="courier">Courier</option>
<option value="impact">Impact</option>
<option value="tahoma">Tahoma</option>
<option value="wingdings">Wing Dings</option>
</select>
<br>
<input type="text" id="textInput" size=33 value="Enter text here.." onKeyUp="setFont();" onChange="setFont();"/>
<div id="output"></div>
</body>
</html>
Though, since you use an image in your implementation this may be unsuitable. In that instance, I'd just
use an image and give it an id. Then, in the setFont function you can just do something like:
url = "http://www.sew-n-print.co.uk/render/font.php"
url += "?text="+byId("textInput").value;
url += "&font="+byId("fontCombo").value;
url += "&color="+byId("colCombo").value;
url += "&size="+byId("sizeCombo").value;
url += "&vadj=50&hadj=25";
byId("myImgId").src = url;
I think that'll work.
<edit>
Yup, that works. Interesting (yet understandable) to see the lag for the image-based text.
Just make sure to remove the units from the size combo box, also the hashes from the colours.
Apologies for the total lack of formatting of the example code output.

Hi,
I have an email through my web hosting service which has told me my database details.
they go
MySQL Hostname: 99.99.999.999
MySQL Username: xxx xxx
MySQL Passwor: aaaaahh
MySQL Server: MySQL 1
I was able to connect to a differnet database which did not have mysql server on it by using the following code
$hostname = "99.99.999.999"; <br />
$password = "aaaaahh"; <br />
$username = "xxx xxx"; <br />
Now i thought that this was simply going to be adding a $server variable on underneath so the complete code would look like this
$hostname = "99.99.999.999"; <br />
$password = "aaaaahh"; <br />
$username = "xxx xxx"; <br />
$server = "MySQL 1"; <br />
<br />
$connection = mysql_pconnect($hostname, $server, $username, $password);<br />
<br />
if (!$connection)<br />
{<br />
die('Could not connect: ' . mysql_error());<br />
}<br />
<br />
echo 'Connected successfully';<br />
mysql_close($connection)<br />
<br />
?><br />
However this doesn't seem to do anything?
Any help would be great
Many Thanks
Dan

Server and hostname usually mean the same thing - the address of the server. In any case, you have the arguments to mysql_pconnect[^] wrong, it should be:
$connection = mysql_pconnect($hostname, $username, $password);
This is assuming the server name is in the $hostname variable.
I suspect $server is actually the database name, so you should select this after connection using mysql_select_db[^].
if(!mysql_select_db($server, $connection)) { ...

Hi,
You are doing it wrong. The correct syntax of mysql_pconnect is:
$connection = mysql_pconnect($server, $username, $password, $client_flags);
So, if you have the hostname, you must use it instead of using ServerName. So, all you have to do is use this piece of code:
$hostname = "99.99.999.999";
$password = "aaaaahh";
$username = "xxx xxx";
$server = "MySQL 1";
$connection = mysql_pconnect($hostname, $username, $password);
if (!$connection)
{
die('Could not connect: ' . mysql_error());
}
echo 'Connected successfully';
mysql_close($connection);
See, I have not used $server anywhere. Not needed. Give it a try.
Enjoy.
