PHP - Do A Select On Two Tables And The Result Allows Access To Fields Of These Two Selected Tables
Im doing a search system and Im having some problems.
I need to search in two tables (news and pages), I already had sucess doing my search system for just one table, but for two tables its not easy to do.
I already use a select statment with two tables using UNION because I want to show number of search results, that is number of returned rows of my first sql statment.
But now I need to do a select statment that allows me to acess all fields of my news table and all fields of my pages table.
I need to acess in my news table this fields: id, title, content, link, date, nViews
I need to acess in my pages table this fields: id, title, content, link
Im trying to do this also with UNION, but in this case Im not having any row returning.
Do you see what I have wrong in my code?
<?php
//first I get my $search keyword $search = $url[1]; $pdo = connecting(); //then I want to show number of returned rows for keyword searched $readALL = $pdo->prepare("SELECT title,content FROM news WHERE title LIKE ? OR content LIKE ? UNION SELECT title,content FROM pages WHERE title LIKE ? OR content like ?"); $readALL->bindValue(1,"%$search%", PDO::PARAM_STR); $readALL->bindValue(2,"%$search%", PDO::PARAM_STR); $readALL->bindValue(3,"%$search%", PDO::PARAM_STR); $readALL->bindValue(4,"%$search%", PDO::PARAM_STR); $readALL->execute(); //I show number of returned rows echo '<p>Your search keyword returned <strong>'.$readALL->rowCount().'</strong> results!</p>'; //If dont return any rows I show a error message if($readALL->rowCount() <=0){ echo 'Sorry but we didnt found any result for your keyword search.'; } else{ //If return rows I want to show, if it is a page result I want to show title and link that I have in my page table //if it is a news result I want to show title and link that I have in my news table and also date of news echo '<ul class="searchlist">'; $readALL2 = $pdo->prepare("SELECT * FROM news WHERE status = ? AND title LIKE ? OR content LIKE ? LIMIT 0,4 UNION SELECT * FROM pages where title LIKE ? OR content LIKE ? LIMIT 0,4"); $readALL2->bindValue(1, '1'); $readALL2->bindValue(2, "%$search%", PDO::PARAM_STR); $readALL2->bindValue(3, "%$search%", PDO::PARAM_STR); $readALL2->bindValue(4, "%$search%", PDO::PARAM_STR); $readALL2->execute(); while ($result = $readALL2->fetch(PDO::FETCH_ASSOC)){ echo '<li>'; echo '<img src="'.BASE.'/uploads/news/'.$result['thumb'].'"/>'; echo '<a href="'.BASE.'/news/'.$result['id_news'].'">'.$result['title'].'</a>'; //if it is a news result I also want to show date on my list //echo '<span id="date">'.$result['date'].'</span>'; echo '</li>'; } echo ' </ul>'; //but how can I do my select statement to have access to my news table fields and my page table fields?? } ?> Similar TutorialsI need help connecting to a Visual FoxPro 9 Database and Table via php.

The linked table is connected to a ODBC source (e.g MS-SQL or 3rd Party ODBC Driver). WebPage(php) Apache, connecting to a ODBC DSN of MS-Access, MS-Access is having linked tables. Linked tables as from another ODBC source. On the PHP Page, When I am trying to connect the ms-access odbc dsn , I am able to connect. But when I query any of the linked tables, PHP is not able to query and is failing. Does php has capabilities to read/write to linked tables in ms-access file. Or it is issue with MS-Access Or is it I am missing something. Microsoft says, its an issue of PHP https://social.msdn....forum=accessdev Requesting you to please share your feedback Regards Rajendra Dewani Hi, i have a database with multiple records. One of those values is an image. When i query the database and i want only the images as a result it gives the result in a field. It then fills up the field horizontal and when there is no more field left it starts a new row. That is what i want. But now i want some extra info next to the picture so i put that in a table with two colums like this: echo '<table border="1" width="400"><td><a href="'.$row['website'].'"> <img src="'.$row['prod_img'].'"> '.$row['prod_name'].' <a href="'.$row['website'].'">'.$row['website'].'</td></table> ';}} But i still want the result to fill up the field and when the field is full i want the next results on a row below this.... Anyone? I have a relational table call sales with prodcut_id and custmer_id tables. I also have a product and customer tables. products table with product_id as an auto increment and customer with custumer_id I want to join through the sales tables all t he fields of row 1 from tables customer and products and pull it at once. This is a member login script and I want to display the products by members. So far I have this query to display the products once the member is login in. $userid is the id of the customer coming from the $userid= $_SESSION['customer_id']; $mysqlSales="SELECT products.* FROM products JOIN sales ON (products.product_id = procuct_id ) WHERE sales.customer_id = '$userid'"; so far that statement is not working where should I have some type of incoherance with the english statement above expressing what I want the query to do. I am trying to simplify my coding work for my website and wanting to make it operate more professionally (as part of my training to better my programming skills, which I know will take a lot of time to do). One of the things I`d like to improve on it is to create tables and fields in my mysql database, but not have to go into phpmyadmin to do it. I know open source programs like Drupal can do this easily so that when you add modules, the user does not have to access the database to set it up. But looking at the codes, I`m unable to figure out how it works. How will I be able to program my code to do something like, I`ll have a form where I enter in what I want the new table to be called, what fields to add in and their specifications, where I could do this by just going into my website as the admin?

Hi there I have 2 tables: Fleet FleetName PlanetName Status Planet PlanetName PlayerName Im trying to write a select query that will search through the fleet table and display Fleet table details Where the PlanetName from the fleet table is = to the PlanetName of the Planet table. Ive tried joining the tables but i dont think the logic quite works.. Code: [Select] mysql_select_db($database_swb, $swb); $query_Fleet = sprintf("SELECT fleet.FleetName, planet.PlanetName FROM fleet, planet WHERE fleet.PlanetName = planet.PlanetName"); $Fleet = mysql_query($query_Fleet, $swb) or die(mysql_error()); $row_Fleet = mysql_fetch_assoc($Fleet); $totalRows_Fleet = mysql_num_rows($Fleet); I want ONLY the Fleets from the planet i am looking at to be displayed not all of them. I have created another query that displays the planet name of the particular one I am looking at as it is parsed from a hyperlink on a previous page. So is there some way i can use both queries together?

Thanks in advance! I'm having a hard time grasping how to select data from several tables. Here's the code Code: [Select] <?php require_once "config.php"; $gamedate = $_SESSION['date']; echo "These umpires are not currently scheduled on this date, and have not asked for the day off:<br />"; $umpirelist = Array('umpire 1 name', 'umpire 2 name', 'umpire 3 name'); $dbc = mysql_pconnect($host, $username, $password); mysql_select_db($db,$dbc); foreach($umpirelist as $data) { //now get stuff from a table $sql = "SELECT calendar.date, calendar.ump1, calendar.ump2, calendar.ump3, calendar.ump4, calendar.ump5, vacation.date, vacation.umpire FROM umps, calendar, vacation WHERE umps.full_name = $data AND $gamedate = `calendar.date` AND $gamedate = `vacation.date` AND $data NOT IN ('calendar.ump1', 'calendar.ump2', 'calendar.ump3', 'calendar.ump4', 'calendar.ump5') AND $data NOT IN ('vacation.umpire') order by umps.full_name asc"; $rs = mysql_query($sql,$dbc); $matches = 0; while ($row = mysql_fetch_assoc($rs)) { $matches++; echo "$row[$data]<br />"; } } ?> The table CALENDAR holds the date of the game, who is playing, and what umpires are schedule for that game. it does have a unique "row_number" column as well, but didn't think I'd need it in this select. The table VACATION has the date, and umpire's name that is on vacation. The table UMPS contains the umpires name (same names as the array in the code) and email addresses and login info. I'm getting this error: Quote Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource on line 152 This is line 152 Quote while ($row = mysql_fetch_assoc($rs)) { Can someone please point me in the right direction as to where I'm going wrong?

Hi guys, This is my first time posting here - im just getting into PHP - i got a question; I have two databases: profile(id, name, interests, dob, gender, join_date, email) interests(id, profile_id, interests) id being the primary key, and profile_id being the foreign key from profile. I want to script that returns profile information and all the matching interests (one user can have multiple interests). This is what i have so far, though it does not work, and i knew it wouldnt; function get_profile($id) { $connection = mysql_open(); $query = "SELECT * "; $query .= "FROM profiles, interests "; $query .= "WHERE profile.id=" . $id; $query .= " AND interests.profile_id=" . $id; $result = @ mysql_query($query, $connection); // Transform the result set to an array (for Smarty) $entries = array(); while ($row = mysql_fetch_array($result)) { $entries[] = $row; } mysql_close($connection) or show_error();; return $entries; } Can someone please advise on how this can be done? or do i need to have two query's one for each table ?
