PHP - How To Implement A Function Into An Array Within An Img Tag?

hi phpfreaks

I have an class that is called "connDatabase" what I want to do with it is either extend it or implement it.
But I don't know which one to use. The other issue I have is say class "a" has three vars that the that the construct
needs to obstantiate and "connDatabase" needs three of its own. How do I obstantiate?

thanks for any help

I was going to use Google analytics API to develop my cms dashboard content but i am unsure that it's the best way to go about it. Does anyone have any suggestions?

Hi All,   How could i implemnent tab strip (jquery ui tab) in php.   Any help in this regard will be appreciated   Thanks Ahsan

I have a website that I did for my uncle and now, the requirements are going beyond my html knowledge and into the realm of server scripting.

My issue is that I need to loop through all the images in a given folder and subfolders and preload them into the html so that the user can view them within a slide show.  There are currently 6 subfolders with over 20 pics in each and there are more pics to come and different folders to add.  I have a media page with the first picture within each category (subfolder) displayed as an eye catcher to the category.  once the user clicks on the image, the slide show will start in a popup.  The problem is that with js, I have to list out every image since it cannot look through a directory listing.  I would like to simply call a server side script that will create an array of the images and preload them so that when the slide show is ran, the appropriate images will show.

I am found numerous scripts for preloading images, written in php, but I am unsure how to implement them and keep a html extension for my pages.  As the site is written entirely in html and javascript, I would like to keep the html extentions if possible. 

As this is my first site, I am sure that server side scripting will become a bigger role, but baby steps are what I need right now.  In addition, if anyone has a good site for learning the server scripting world, I would greatly appreciate the reference.

Basically I am submitting and retrieving data from a 3rd party's API. But every time I submit a form, it gives me this error.

Access to XMLHttpRequest at 'https://3rdpartywebsite.com/api' from origin 'https://mywebsite.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

 

So I have been researching and there seems to be so many different answers. I have tried adding this code to the page but still get an error.

<?php
// ADD THIS CODE ON THE VERY TOP OF THE PAGE I AM SUBMITTING THE FORM.

header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Credentials: true");
header("Access-Control-Max-Age: 1000");
header("Access-Control-Allow-Headers: X-Requested-With, Content-Type, Origin, Cache-Control, Pragma, Authorization, Accept, Accept-Encoding");
header("Access-Control-Allow-Methods: PUT, POST, GET, OPTIONS, DELETE");
?>

 

I have also tried to add this to .htaccess file and still get the same error.

Header add Access-Control-Allow-Headers "origin, x-requested-with, content-type"
Header add Access-Control-Allow-Methods "PUT, GET, POST, DELETE, OPTIONS"

 

I was wondering what am I doing wrong? What's the correct way of implementing CORS to my site?

I have a while loop that fetches data from the database and prints it out organized in a table.

Now I want to implement a voting functionality, the problem I'm encountering is, once I've printed out a list of tables one table after other with the while loop I need to figure out a way to tell the query TO WHICH of those tables to ADD or SUBTRACT the vote.

I thought of implement a hidden id field into the while loop of contributions, the id field would be fetched from the auto_increment field in the contribution table in the MySQL database.

Since the id field is unique there can be no misunderstandings to which table to add the vote.

My question how can I do exactly that? How can I add a hidden id field to the while loop with the table WHICH I then can pass along to the voting script.

Here's the while loop:

while ($row = mysqli_fetch_array($data)) 

{

echo "<table padding='0' margin='0' class='knuffixTable'>";

echo "<tr><td width='65px' height='64px' class='avatar_bg' rowspan='2' colpan='2'><img src='$avatar_path' alt='avatar' /></td><td class='knuffix_username'><strong>" . $user_name;

echo "</strong><br />" . $row['category'] .  " | " . date('M d, Y', strtotime($row['contributed_date'])) . "</td></tr><tr><td>";

echo "<form action='' method='post'>

<input type='submit' name='plusVote' value='Y' />

<input type='submit' name='minusVote' value='N' />

</form></td><td class='votes'>Y[ - ] | N[ - ]</td></tr>";

echo "<tr><td class='knuffix_name' colspan='3'><strong>" . htmlentities($row['name']) . "</strong><br /></td></tr>";

echo "<tr><td colspan='2' class='knuffix_contribution'><pre>" . $row['contribution'] . "</pre><br /></td></tr>";

echo "</table>";

}


If I simply add $row['con_id'] it's obviously going to be echo'd out, what is the right practice to have it hidden?

Hi again people!

I found this code that codes for a countdown timer.
My problem is, how do I implement it?
I've found similar codes that leave me dazzled as I try to get them to work.

The URL from which I found this is:
http://scripts.franciscocharrua.com/server-side-countdown-clock.php

The code is:

Code: [Select]
function countdown_clock(year, month, day, hour, minute, format)
         {
         //I chose a div as the container for the timer, but
         //it can be an input tag inside a form, or anything
         //who's displayed content can be changed through
         //client-side scripting.
         html_code = '<div id="countdown"></div>';

         document.write(html_code);

         Today = new Date();
         Todays_Year = Today.getFullYear() - 2000;
         Todays_Month = Today.getMonth();

         <?
         $date = getDate();

         $second = $date["seconds"];
         $minute = $date["minutes"];

         Todays_Date = (new Date(Todays_Year, Todays_Month, Today.getDate(),
                                 Today.getHours(), Today.getMinutes(), Today.getSeconds())).getTime();

         countdown(year, month, day, hour, minute, (Todays_Date - Server_Date), format);
         }

function countdown(year, month, day, hour, minute, time_difference, format)
         {
         Today = new Date();
         Todays_Year = Today.getFullYear() - 2000;
         Todays_Month = Today.getMonth();

         //Convert today's date and the target date into miliseconds.

         Todays_Date = (new Date(Todays_Year, Todays_Month, Today.getDate(),
                                 Today.getHours(), Today.getMinutes(), Today.getSeconds())).getTime();
         Target_Date = (new Date(year, month, day, hour, minute, 00)).getTime();

         //Find their difference, and convert that into seconds.
         //Taking into account the time differential between the client computer and the server.
         Time_Left = Math.round((Target_Date - Todays_Date + time_difference) / 1000);

         if(Time_Left < 0)
            Time_Left = 0;

         switch(format)
               {
               case 0:

                    document.all.countdown.innerHTML = Time_Left + ' seconds';
                    break;

I've tried saving the file as a php file and html file, but to no avail...

I have two files with coding in. One of them is the HTML form file:

Code: [Select]
<?php
<html><head><title>Car Accident Program</title></head>
<body>
<!----In this block of code I am creating a form with 4 text boxes and a button as well as user prompts to get user inputted values to work with---->

<form action="Car.php" method="post">

<input type="text" size = "45" name="weeks"><br>
<input type="submit" value="Submit report">

</body>
</html>
and the PHP/Validation file:

Code: [Select]
<!----In this block of code, I am creating a PHP script that gets the user inputted values and can display them in a report as well as use an IF statement to show an extra line to appear if the user enters an age below 18 or a time since accident below 1 week or if they miss out a field or more---->
<?php

$firstname= $_POST ['firstname'];

echo ($msg)
?>


</body>
</html>
<html>

I was wondering how, if suitable, I would add a cookie or session into coding like this.

Any help is appreciated,

Hello Guys,

I have a question

I have the following function that is located in a different file. I want to be able to use the $lat and $long in my main page how would I code it?

Code: [Select]
function toCoordinates($all_address)
{
    $bad = array(
        " " => "+",
        "," => "",
        "?" => "",
        "&" => "",
        "=" => ""
    );
    $all_address = str_replace(array_keys($bad), array_values($bad), $all_address);
    $data = new SimpleXMLElement(file_get_contents("http://maps.google.com/maps/geo?output=xml&q={$all_address}"));
    $coordinates = explode(",", $data->Response->Placemark->Point->coordinates);
    return array(
        "latitude" => $coordinates[0],
        "longitude" => $coordinates[1]
    );
}

Tried this but it didn't work

$all_address2 = toCoordinates($all_address);

echo "$all_address2;

Please advise...
Thanks, Dan

Hey Guys,

I am hoping you can help me find out why a function of mine is only returning 1 record when I am asking for 10.

Here is the function I am using to get the data.

When I run the $sql that is printed in phpmyadmin.... I get then records. But when I print the $event_data I am only getting 1 record.

Any help would be greatly appreciated


function get_events($data)
{
//print_r($data);
$lat = $data['lat'];
$long = $data['long'];
$offset = $data['offset'];
$radius = $data['radius'];
$amount = $data['amount'];

//the events query
$sql = sprintf("SELECT *, ( 3959 * acos( cos( radians('%s') ) * cos( radians( latitude ) ) * cos( radians( longitude ) - radians('%s') ) + sin( radians('%s') ) * sin( radians( latitude ) ) ) ) AS distance FROM events WHERE `status` = '0' HAVING distance < '%s'  ORDER BY distance LIMIT $amount OFFSET $offset",
  mysql_real_escape_string($lat),
  mysql_real_escape_string($long),
  mysql_real_escape_string($lat),
  mysql_real_escape_string($radius));

//debugging
print_r($sql);

$event_data = array();
$event_data = mysql_fetch_array(mysql_query($sql));

//debugging
print_r($event_data);

return $event_data;

}

Hi im having some trouble when i try to add values to an array from a function. The added value will not stay saved.
fun1 will display both firstname and surname but when i call fun2 after calling fun1 i just get the firstname.

I would like to have it so the array is updated and stays updated untill it is cleared or over written.

Any help with this would be greatly appreciated. i am using codeigniter if that makes any difference.

Thanks



<?php

class Test extends Controller
{
    var $data1 = array(
    'firstname' => 'craig'
    );

    function fun1()
    {
        global $data1;
        $this->data1['surname'] = 'brute';
        echo "<pre>";
        print_r($this->data1);
    }

    function fun2()
    {
        global $data1;
        echo "<pre>";
        print_r($this->data1);
    }

}

I hope I'm not being a vampire here sucking the life out of you guys, but I can't find any resources in google that explains how to properly use this function in a mysql array. All it does is add a url for any urls added in plaintext.

Code:
---
<?php

function hyperlink ($string) {
$string = preg_replace('#(^|\s)([a-z]+://([^\s\w/]?[\w/])*)#is', '\\1<a href="\\2" target="_blank">\\2</a>', $string);
$string = preg_replace('#(^|\s)((www|ftp)\.([^\s\w/]?[\w/])*)#is', '\\1<a href="http://\\2" target="_blank">\\2</a>', $string);
$string = preg_replace('#(^|\s)(([a-z0-9._%+-]+)@(([.-]?[a-z0-9])*))#is', '\\1<a href="mailto:\\2">\\2</a>', $string);
return $string;
}

// mysql connection

$result = mysql_query("SELECT * FROM top_web_articles ORDER BY ID DESC");

echo "<table border='0'>";

while($row = mysql_fetch_array($result))
  {
  echo "<tr>";
  echo "<td class='newstitle' align='left' valign='top' bgcolor='#D6D6D6'>".$row['Category']."</td></tr>";
  echo "<td class='newstitle' align='left' valign='top' bgcolor='#D6D6D6'>". $row['ArticleName'] ."</td></tr>";
  echo "<td class='newstitle' align='left' valign='top' bgcolor='#D6D6D6'>"hyperlink(. $row['ArticleDescription'] .);"</td></tr>";
  echo "<tr><td  class='newstitle' align='left' valign='top' bgcolor='#D6D6D6'><a href='". $row['URL'] . "' target='_blank'><img src='http://www.thenewsguys.ca/images/read entire article.png' alt='' width='130' height='11' border='0' /></a></td>";
  echo "</tr>";
  echo "<td align='left' valign='top'>&nbsp;</td>";
}
echo "</table>";

mysql_close($con);
?>
