You can use file_get_contents()
(http://php.net/manual/en/function.file-get-contents.php)
<?php
$homepage = file_get_contents('filename.txt');
echo $homepage;

I am developing an online examination system. Everything works fine but the questions are selected and displayed from question number one to the last question. I wanted to do the following:
Select the questions and display them one after the other at random.
Add a skip button so that students can skip any question they can't answer and it will be rolled back to them later.
Give a time to the answering session so that when the time is up it will stop the student.
This is my code for the question selection.

I am having two drop down lists on a html page. The data is coming from a mysql database and contains information like latitude, longitude and address. The user selects one item from the drop down and clicks on submit.
At this stage, I want to display a google map and put a marker at the latitude and longitude. Then, when the user selects the option from second drop down, I want to just add a marker on that map.
Currently, I am able to load the map once he clicks the submit from first drop down but all the options I tried to drop the pins are not working.
Here is the code I have achieved till now:
<?php
error_reporting(E_ALL);
ini_set('display_errors', '1');
require_once('auth.php');
include ('LoginConfig.php');
include ('FetchAgentDetails.php');
include ('FetchDeliveryDetails.php');
?>

SQL/PHP query works in PHPmyAdmin but not the site.
I notice that many have had this problem but admittedly I am not as advanced as some of the coders on this site...yet. =) I humbly request any experience you may have laying around :P Thank you.

I'm not sure about MySQL, but I know that in SQL when you do an aggregate function, like SUM(Kills), then you can't reference the row via $row['kills']. I don't know if this is your problem, but you could try doing SUM(Kills) as 'kills' in your SELECT statement. Doing this for your aggregate SELECTs will allow you to reference them all this way.
I have a generated php table which I would like to apply style in my style sheet, so for example top:15px, left:10px ect..., not sure how call the table and link it with css -
echo "<table border=1>";
for ($i=0;$i<count($calls);$i++){
for ($j=0;$j<count($days);$j++){
$k = $days[$i].$times[$j];
if (array_key_exists($k,$date)){
echo "<td colspan='{$date[$k][1]}'>".
"{$date[$k][0]}</td>";
$j+=$date[$k][1]-1;
}else
echo "<td style='color:gray'>$k</td>";
}
echo "</tr>";
}
echo "</table>";
any help much appreciated, thank you
echo '<table style="top: 15px; left:10px;">';
or
echo '<table class="someClass">';
and then use CSS
.someClass{
top: 15px;
left: 10px;
}
Give the table an id
echo "<table id=\"my_table\" border=1>";
And then use this in the <head> tag of the document:
<style type="text/css">
#my_table {
top: 15px;
...
}
</style>
echo "<table style=\"border: 1px; top:15px; left: 10px;\">";
Is this statement not working?
echo "<table border=1 style=\"top:15px; left:10px\">";
for ($i=0; $i<count($calls); $i++) {
for ($j=0;$j<count($days);$j++) {
$k = $days[$i].$times[$j];
if (array_key_exists($k,$date)) {
echo "<td colspan='{$date[$k][1]}'>".
"{$date[$k][0]}</td>";
$j+=$date[$k][1]-1;
} else {
echo "<td style='color:gray'>$k</td>";
}
}
echo "</tr>";
}
echo "</table>";
I am fetching data from the following database:
I have arduino-box that send that data.
And display the data with this CSS & HTML code:
<div class="event">
<img src="http://dummyimage.com/80x70/f00/fff.png" alt="picture" />
<p>Room 2</p>
<p class="patient-name">Jon Harris</p>
<p class="event-text">This is a pixel. A flying pixel!</p>
<p class="event-timestamp">feb 2 2011 - 23:01</p>
</div>
.event {
display:block;
background: #ececec;
width:380px;
padding:10px;
margin:10px;
overflow:hidden;
text-align: left;
}
.event img {
display:block;
float:left;
margin-right:10px;
}
.event p {
font-weight: bold;
}
.event img + p {
display:inline;
}
.patient-name {
display:inline;
color: #999999;
font-size: 9px;
line-height:inherit;
padding-left: 5px;
}
.event-text{
color: #999999;
font-size: 12px;
padding-left: 5px;
}
.event-timestamp{
color: #000;
padding-left: 5px;
font-size: 9px;
}
Here is my PHP code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>DASHBOARD - Arduino 3</title>
<link rel="stylesheet" type="text/css" href="css/style.css">
</head>
<body>
<?php
$con = mysql_connect("localhost","*****","***");
if(!con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("arduino_db",$con);
$result = mysql_query("SELECT * FROM events");
//Start container
echo " <div id='background_container'> ";
while($row = mysql_fetch_array($result))
{
echo "<div class='event'>";
echo "<img src='img/ev_img/red.jpg' alt='picture' />";
echo "<p>" . $row['inneboende'] . "</p>";
echo "<p class='patient-name'>" . "$row['overvakare']" . "</p>";
echo "<p class='event-text'>" . "$row['handelse']" . "</p>";
echo "<p class='event-timestamp'>" . "$row['tid']" . "</p>";
echo "</div>";
}
//end container
echo "</div>"
mysql_close($con);
?>
</body>
</html>
The arduino box is sending data to the database.. lets say every 3sec. I dont want to press F5 every 5sec to get the new data. Should I use AJAX for this? I have read some AJAX on the net, but I haven´t find any good tuts for it.
Put this in a separate php file, e.g. getEvents.php:
<?php
$con = mysql_connect("localhost","*****","***");
if(!con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("arduino_db",$con);
$result = mysql_query("SELECT * FROM events");
while($row = mysql_fetch_array($result))
{
echo "<div class='event'>";
echo "<img src='img/ev_img/red.jpg' alt='picture' />";
echo "<p>" . $row['inneboende'] . "</p>";
echo "<p class='patient-name'>" . "$row['overvakare']" . "</p>";
echo "<p class='event-text'>" . "$row['handelse']" . "</p>";
echo "<p class='event-timestamp'>" . "$row['tid']" . "</p>";
echo "</div>";
}
mysql_close($con);
Then, load jquery and put the following in the head of the page:
<script type="text/javascript">
$(document).ready(function() {
$.get('getEvents.php', function (data) {
$('#background_container').html(data);
});
});
</script>
Note: This is not the exact code you should use, take a look at it and change it so it works correctly for you.
If you are just trying to refresh the page every 5 seconds, you should use javascript and look at setTimeout:
setTimeout("location.reload(true);",5000);
5000 is equal to 5 seconds.
