PHP - Sqlite + Website

I'm trying to conditionally add a table to a select query using the join, but I always get an "no such table"  error.  I'm not at all sure if the syntax is correct, so I decided to ask.    I'm using the sqlite C API interface and my tables and query were constructed using sprintf, so please ignore any %d, %s that may appear

CREATE TABLE IF NOT EXISTS tbl_master
(
     id INTEGER PRIMARY KEY AUTOINCREMENT,
     volume TEXT(16) UNIQUE NOT NULL DEFAULT '',
     note   TEXT(%d) NOT NULL DEFAULT '',
     items INTEGER NOT NULL DEFAULT 0
);
 
CREATE TABLE IF NOT EXISTS tbl_file
(
      id INTEGER PRIMARY KEY AUTOINCREMENT,
      volume_key TEXT(16) NOT NULL DEFAULT '',
      name TEXT(%d),
      size TEXT(20),
      type TEXT(4),
      path TEXT(%d),
      file_id INTEGER
);
 
CREATE TABLE IF NOT EXISTS tbl_hash
(
     id INTEGER PRIMARY KEY AUTOINCREMENT,
     hash TEXT(33) NOT NULL DEFAULT '',
     volume_key TEXT(16) NOT NULL DEFAULT '',
     file_key INTEGER NOT NULL DEFAULT 0
);
 
CREATE TABLE IF NOT EXISTS tbl_media
(
       id INTEGER PRIMARY KEY AUTOINCREMENT,
       runtime TEXT(10) NOT NULL DEFAULT '',
       frame TEXT(12) NOT NULL DEFAULT '',
       type_key TEXT(4) NOT NULL DEFAULT '',
       hash_key TEXT(33) NOT NULL DEFAULT '',
       volume_key TEXT(16) NOT NULL DEFAULT '',
       file_key INTEGER NOT NULL DEFAULT 0
);

I milled over a few JOIN tutorials, but I'm still unclear on the exact usage of JOIN; I'm trying to add the media table if the file type is a vid, snd, or pix, but I need file information regardless.  I've tried various flavors of the following query, but each time I get the table doesn't exist error.  Selects, deletes, updates, inserts work on all tables, so I'm guessing my syntax is wrong with the JOIN.

SELECT tbl_file.*, tbl_hash.hash
  FROM tbl_file AS f, tbl_hash AS h
  LEFT OUTER JOIN tbl_media AS m
  ON  ((f.type='VID' OR f.type='SND' OR f.type='PIX')
  AND m.file_key=f.file_id)
  WHERE ((f.volume_key=tbl_master.volume
  AND (h.volume_key=tbl_master.volume AND h.file_key=f.file_id)))
  ORDER BY f.path ASC;

Any ideas on how to pull off what I'm trying to do would be greatly appreciated.  Thank you for your time.      

Hi everyone this is my first post so I'm sorry if I've posted it in the wrong section!

Before I begin I'd like to point out that I'm not just here to get someone to produce what I want for me! I have a genuine interest in this forum and I'm slightly surprised and disappointed in myself that I hadn't took the time to join sooner!

Anyway to the point of this post: (Please bare with me I think I'll need to justify the use of SQLite)

I am currently undergoing a University gorup project that uses wireless sensors to collect environmental data such as, Temperature, Humidity, Light levels and Dew point. This application is programmed in Python and it collects these pieces of data (every 30 seconds) and places them into an SQLite database.

My job is to now graphically plot/show the data that the Python program collects and stores in the SQLite database on a web page. I'm using Ubuntu and have successfully installed LAMP, SQLite3 and the SQLite PD0 driver.

I have also successfully established a connection to the SQLite database as well as displaying the data on a web page (locally - thats all I need!) in the form of a simple HTML table through the use of the following PHP script:

Code: [Select]
<?php
  try
  {
    //open the database
    $db = new PDO('sqlite:/var/databases/307Code/python/readings.db');

    //now output the data to a simple html table...
    print "<table border=1>";
    print "<tr><td>Date & Time Recieved</td><td>Node</td><td>Temp</td><td>Hum</td><td>Light</td><td>Dew</td></tr>";
    $result = $db->query('SELECT * FROM readingstable');
    foreach($result as $row)
    {


      print "<tr><td>".$row['Recieved']."</td>";
      print "<td>".$row['Node']."</td>";
      print "<td>".$row['Temp']."</td>";
      print "<td>".$row['Hum']."</td>";
      print "<td>".$row['Light']."</td>";
      print "<td>".$row['Dew']."</td></tr>";
    }
    print "</table>";

    // close the database connection
    $db = NULL;
  }
  catch(PDOException $e)
  {
    print 'Exception : '.$e->getMessage();
  }
?>
What I'm now looking to do is the following:

1. Display the data from the SQLite database in the form of line graphs (I've seen that I may need to convert the data to XML?)
2. Make the application asynchronous, preferably every time a new entry is added to the SQLite database the line graph(s) update without a user needing to refresh the browser.
3. The SQLite database is storing a ridiculous floating point number for the time field in the database, for example: "2012-03-23 16:49:42.440818" is a entry in the SQLite database. Is there any way to omit the .440818 through the use of PHP? Or will I need to edit the Python script?

Also one thing to note: The person in my group who built the Python script didn't build it to make the SQLite database give each database entry a unique ID/Primary key.

Any tips/advice/help would be massively appreciated!

Regards,

Rich

I am trying to convert and old website from mysql database to sqlite. One of the chores it must do is collect information from the database and put it in a list/menu select box on a page so the user can choose which item to pursue.   In the following (incomplete) snippit, I am doing something incorrectly because the sql query does get the proper information (I can put it in a table on the page just fine). But I'm having trouble getting the information into the select options on a list/menu. It appears to be putting them all, one after the other in the first option spot. The last one seems to be the only one of 6 or 7 that shows up.   It's been 10 or 12 years since I've messed with php, so I think I'm way behind... any help would be appreciated.   --------------------------- <form action="sqlPropDisplay.php" method="post" id="Residential">

hello dear php-experts,

i fairly new to simple_html_dom usage and methods. I know a little the parser,
 
i want to gather some information from this site:

https://europa.eu/youth/volunteering/organisations_en#open

is this possible to get the content - of let us say 10 or 20 last records on that page - and subesquently to store it in my mysql - db!?

<?php
// Report all PHP errors (see changelog)
error_reporting(E_ALL);

include('inc/simple_html_dom.php');

    //base url
    $base = 'https://europa.eu/youth/volunteering/organisations_en#open';

    //home page HTML
    $html_base = file_get_html( $base );

    //get all category links
    foreach($html_base->find('a') as $element) {
        echo "<pre>";
        print_r( $element->href );
        echo "</pre>";
    }

    $html_base->clear(); 
    unset($html_base);

?>

 

I have the above code and I'm trying to get certain elements of the page but it isn't returning anything. 

 

Is it possible that certain PHP functions might be disabled on the server to stop that?

The above code works perfectly on other sites.

 

Is there any workaround?

 

 

btw:  i have created a small snipped as a proof of concept to run this with Python and BeautifulSoup - 

 

import requests
from bs4 import BeautifulSoup
 
url = 'https://europa.eu/youth/volunteering/organisations_en#open'
response = requests.get(url)
soup = BeautifulSoup(response.content, 'lxml')
print(soup.find('title').text)
block = soup.find('div', class_="eyp-card block-is-flex")

 

and this.... 

 

European Youth Portal
>>> block.a
<a href="/youth/volunteering/organisation/48592_en" target="_blank">"Academy for Peace and Development" Union</a>
>>> block.a.text
'"Academy for Peace and Development" Union'
 
>>> block.select_one('div > div > p:nth-child(9)')
<p><strong>PIC:</strong> 948417016</p>
>>> block.select_one('div > div > p:nth-child(9)').text
'PIC: 948417016'

 

what is aimed in the end - i want to gather the first 20 results of the page - and put them in to a sql-db or alternatively show the information in a little widget 

I'm trying to make a League of Legends (a video game) community website, both as a personal project and for practice.
Now the game has a lot of champions, each of whom have 5 unique abilities. Now, I thought about manually inputting all the details about each champion into a MySQL database, but that would long and tedious, and I don't really have the time for it now. Also, the game patches very oftern (like, once every 2 weeks) which changes many of the stats, etc. of the champion, and it is not possible for me to keep manually updating these every time there is a patch.

Fortunately, there is a League of Legends Wiki which has all the data I need in their specific champion pages, which they keep updated per patch. So I was wondering if there was any way to get the data from the divs in the wiki, and have it display on my site. What I want to do in my website is that whenever someone types a champion's name (in a post or whatever), I want it to display a hover-over dialog with some of the champions details. And a lot of other features such as that.

In plain English I need a way to :
> Tell PHP to go to the wiki's source code on a specific page
> Find a specific div container
> Get X data from there
> Pass X data into a function to display the hover-over

I think this way, I would not have to maintain a database as I can leech off the wiki's data.
I have not coded anything like this before, so I would like a few pointers as to how to achieve this. Any help will be appreciated!

I tried searching on google but couldn't find any relevant information, please redirect me to relevant source or help me with the code.

I want to pass a domain name in text field which will be scanned and then the script will display entire site map.

Not external links or links on a page. Sorry it is not easy for me to explain.

Eg. if i pass abc.com

Script will display

abc.com/12/adn.php
abc.com/asd/asd/
etc

Whatever their url format is.

All the links on that domain.

hello
My database is in a same server with seperate domain name , then I want to insert from website1 mysql data on website2 mysql data.

Is it possible to download files from a website to my online websites root directory? reason I'm asking is because I have been downloading large video files to my computer which take about 20 minutes!! Then I use FTP to upload them to my site but it takes about 2-3 hours per video!! I was looking for a faster way! All help would be great!

My code on website is not validate on W3 Validator.   <?xml version="1.0" encoding="ISO-8859-1"?>

Hi, I haven't used any php for a while, but i am making a website, and i need some advice on how to do the following:

I want the website to change an image once every 24 hours, the image will revert back to the original image after 2 minutes.

Does anyone have an idea how I could start doing this?

Hello everybody! I have been asked by a customer to develop a GTP website (Get To Pay, those websites where people earn money from clicking on ads). I managed to write the backend, signup and login but I am unsure how the ads part, with built-in user-tracking works and fallback link works.   I would really appreciate any kind of help. Thank you very much! P.S. For the user tracking I was thinking of sessions with matching ip and user agents together with an anti-proxy online service (e.g. MaxMind, Proxystop, ...) 

I am working on a website and I am at a standstill. I would rather speak to someone one on one but its been very difficult to find someone that could help. I have the scripts that I want but when I add the scripts to the mainpage everything stops working. I really don't want to go to wordpress because I am almost done with this one. Thanks.

This would be an example of a  page I'm referring to: http://www.curse.com...other-downloads   I want to get the file name and compare it to another name (to see if they are the same or not). I have no idea how to access that page from my website. I'm guessing PHP would be best although if you don't think so tell me what you think would be better  (I was thinking javascript but don't think that's cross-site compatible). Is there a  PHP function to get the value of the href which is in this case (as of this posting) "Railcraft 9.4.0.0".   I used inspect element to see the code of the page but have no idea if this is possible or if I'm even going about this the right way. The code would have to work on this entire website (all pages have the smae layout as this one though! Any help is greatly appreciated!    

Hi there

Hello everyone and thank you for reading this.   My goal: Build a site like sportingnewschicago.com   What it does? It has different sectiions of different teams. Then it displays the tittle of the news and makes them be able to click on to go to the news site. The site some how checks a list of sites and post them on their respected section. But only ones that have not already been listed.   What i want to do?  Well i want to try to learn how to do this. Is this something i can make with the help of members here? It would only have index.php and thats it.   Please let me know if anyone would be interested in teaching me as i do it. If not i would understand. Thank you.
