Hi! I’m Starx

Question 1

Question by user1304197

I have a $_POST ($_POST[‘durationChosen’]) which is a time and its format is ’00 Hrs 00 Mins 00 Secs’. Now I still want to display this format in the textbox but on the next page I want $_POST[‘durationChosen’] I want the format to be ’00:00:00′. How can I do this?

An example is in the textbox I have ’01 Hrs 30 Mins 15 Secs’ but in next page I want it formatted so its ’01:30:15′. Can this be done?

Answer

Answer by MichaelRushton

MichaelRushton

Try this:

<?php

  $array = sscanf($_POST['durationChosen'], "%u %s %u %s %u %s");

  $time = date('H:i:s', strtotime($array[0] . ':' . $array[2] . ':' . $array[4]));

Edit to reflect comment of acceptance below:

<?php

      $time = str_replace(array(' Hrs ', ' Mins ', ' Secs'), array(':', ':', ''), $_POST['durationChosen']);

Answer

Answer by Starx

Starx

You might want to read the manual. The problem with your coding is that, you are using short notation of time, which the data function does not understand. Read here

A simple way to get around this

$time = $_POST['durationChosen'];
$time= str_replace("Hrs", "Hour", $time);
$time= str_replace("Mins", "minutes", $time);
$time= str_replace("Secs", "seconds", $time);

$time = strtotime($time);
echo date($time, "H:i:s");

I have a table structure, where I can’t access jsp file to add class files. I have to manage it through css. In this case, I need to apply background color for 1st table all th’s. Not to nested table th’s. How can we do with css? Example : http://jsfiddle.net/qdDnJ/

Answer

Answer by Starx

Starx

The simplest way I know is to use the child selector

#yourtableId > tbody > tr > th { background: red; }

Question 3

Question by Matt

Matt

I’ll use an example to illustrate this:

class Company {

}

class Person {

}

Company and Person hold a many to many relationship. A Person can belong to multiple Companies and a Company can hold multiple People.

Would I then need to create a third class:

class CompanyPerson {

}

or should the company handle it:

class Company {
    function add_person() {

    }
}

or maybe the Person should?

class Person {
    function add_to_company() {

    }
}

Answer

Answer by Starx

Starx

This depends on the use case, but generally many to many object relationship can be deployed using a reference class

class CompanyPersonRelationship {
    public $company;
    public $person;
}

So now, both company and person can keeps track of their relationship lie

class Company {
   public $persons = array();   
}

class Person {
   public $companies = array();
}

Question 4

Question by Jeff

Jeff

This is probably an easy thing to do but I’m an amateur and things just aren’t working for me.

I just want to check and see if a row exists where the $lectureName shows. If a row does exist with the $lectureName somewhere in it, I want the function to return “assigned” if not then it should return “available”. Here’s what I have. I’m fairly sure its a mess. Please help.

function checkLectureStatus($lectureName)
{
 $con = connectvar();
 mysql_select_db("mydatabase", $con);
 $result = mysql_query("SELECT * FROM preditors_assigned WHERE lecture_name='$lectureName'");
  while($row = mysql_fetch_array($result));
  {
     if (!$row[$lectureName] == $lectureName)
     {
         mysql_close($con);
         return "Available";
     }
      else
     {
        mysql_close($con);
        return "Assigned";
    }
}

When I do this everything return available, even when it should return assigned.

This ought to do the trick: just limit the result to 1 row; if a row comes back the $lectureName is Assigned, otherwise it’s Available.

function checkLectureStatus($lectureName)
{
    $con = connectvar();
    mysql_select_db("mydatabase", $con);
    $result = mysql_query(
        "SELECT * FROM preditors_assigned WHERE lecture_name='$lectureName' LIMIT 1");

    if(mysql_fetch_array($result) !== false)
        return 'Assigned';
    return 'Available';
}

Answer

Answer by Starx

Starx

Use mysql_num_rows(), to check if rows are available or not

$result = mysql_query("SELECT * FROM preditors_assigned WHERE lecture_name='$lectureName' LIMIT 1");
$num_rows = mysql_num_rows($result);

if ($num_rows > 0) {
  // do something
}
else {
  // do something else
}

Question 5

Question by john

I used the following code to remove script, link tags from my string,

$contents='<script>inside tag</script>hfgkdhgjh<script>inside 2</script>';
$ss=preg_replace('#<script(.*?)>(.*?)</script>#is', '', $contents);
echo htmlspecialchars($ss);

it works fine. But can I use anything that similar to html parsing rather than preg_match for this?

Answer

Answer by Starx

Starx

Here are few things you can do

htmlspecialchars() can prove those tags useless
striptags() removes all HTML tags

But the technique you are using is the correct one. However here is a improved version for that

echo preg_replace('/<scriptb[^>]*>(.*?)</script>/is', "", $contents);

Question 6

Question by colindunnn

colindunnn

The code below is a simplified version of my website. On my site, the image width varies from page to page and the text is around 100 words. That means the paragraph stretches the DIV to be wider than the image. Using only CSS, is it possible to shrink the DIV and the paragraph to the width of the image?

JSFiddle here

Example of what I’m trying to describe here. Top is what I’m getting, bottom is what I want.

HTML

<div>
    <img src="image.jpg" />
    <p>Lorem ipsum dolor sit amet.</p>
</div>

CSS

div {
   display: inline-block;
   }

And for doing anything table related I shall forever shame myself: http://jsfiddle.net/WM6hK/3/

display: table;
border: 1px solid red;
width: 1%;
}

p {
border: 1px solid blue;

Answer by Starx

Right now its not possible, using CSS

Using jQuery, its as easy as this

$("div").width($("div img").width());

Question 7

Question by Lily Evans

Lily Evans

I’ve built an intro page for my website (it’s a .swf file) and I’m trying to embed it into an .html file, but the html code won’t allow me to resize the file (I want the file to take up the whole page, so I tried resetting the height and width parts of the object tag to 100% – it didn’t work)
someone told me that the best way to resize the file would be by using javascript. How would I do this?

the code is as follows:

<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,0" width="550" height="400" id="intro to elianas website" align="middle">
<param name="allowScriptAccess" value="sameDomain" />
<param name="movie" value="intro.swf" />
<param name="quality" value="high" />
<param name="bgcolor" value="#1C140D" />
<embed src="intro.swf" quality="high" bgcolor="#1C140D" width="100%" height="100%" name="intro" align="center" allowScriptAccess="sameDomain" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" />
</object>

Answer

Answer by Starx

Starx

You also need to provide the height and width for the Object as well.

<object width="100%" height="100&">
    <param name="movie" value="file.swf">
    ..
    <embed src="intro.swf" width="100%" height="100%" />
</object>

Question 8

Question by elcodedocle

elcodedocle

I’m implementing a php interface to process a .php file containing a bunch of define sentences defining constants with text values to translate by somebody.

The input is parsed sentence by sentence and shown in the interface to the translator who will input the translation in a html textarea and send it to the server

By the end of the process an output file would be generated, identical to the input .php file, only with the define values translated.

E.g. processing an input file ‘eng.php’ like this:

<?php
define ("SENTENCE_1", "A sentence to translate");
?>

would give the translated output file ‘spa.php’ like this:

<?php
define ("SENTENCE_1", "The same sentence translated to spanish");
?>

For this I would like to know:

1) What is the best way to parse the input file to get the constant names and values in an array? (Something like $var[0][‘name’] would be “SENTENCE_1” and $var[0][‘value’] would be “A sentence to translate”)

2) Would it be possible to get the translation from google translator shown in the input textarea as a suggestion to edit for the person who is translating it? How? (I read google translator api v1 is no longer available and v2 is only available as a paid service. Are there any free alternatives?)

What about that?

Answer

Answer by Starx

Starx

Use get_defined_constants() to get the list of all the defined constants.

To get userdefined constant specially

$allconstants = get_defined_constants(true);
print_r($allconstants['user']);

Remove <style type="text/css"> and </style> from your css file.

Answer

Answer by Starx

Starx

You have placed your CSS code in the style sheet along with the <style> tags. You shouldn’t do that when attaching an external CSS stylesheet. You can directly define the styles.

Remove

<style type="text/css"> & </style> from your file style.css

Question 10

Question by Umm….

Umm….

So basically, I have a div which is runat=”server”

<div id="results" runat="server" class="results"></div>

Now, I add HTML to this using jQuery.

$('.results').html('Some crazy data');

However, when I try to access the data in this DIV using C#, it says the DIV has no contents.

string myResults = results.innerHtml;

myResults is empty.

Can someone help me out? I’ve never seen this behavior before.

Many Thanks!

Answer

Answer by amit_g

You may be looking for something like this…

<div id="results" runat="server" class="results"></div>
<input type="hidden" id="hiddenResults" runat="server" class="hiddenResults" />

$('.results').html('Some crazy data');
$('.hiddenResults').val('Some crazy data');

Now you can access the data on server

string myResults = hiddenResults.Value;

Answer

Answer by Starx

Starx

Instead of mixing up jQuery and Javascript. Try

var myResults = $(".results").html();

Just to verify everything is correct, see if your results is defined as below

var results = document.getElementById("results");
var myResults = results.innerHtml;

If you trying to get the value of results to the server, it is not possible through jQuery or Javascript unless send an AJAX request.
