Trying to translate a MySQL query into a PHP query - php

I'm still kinda new to PHP and MySQL and I've tried so many times to do this and I just can't figure out how.
I have a query that returns the results I want in PHPMyAdmin as a straight MySQL query but I'm trying to get this to generate on a webpage using a PHP $query and I just can't get the syntax right.
this is the working MySQL query:
SELECT fk_toon_no, fk_actor_no, actor_no, actor FROM cartoon_characters,
characters WHERE fk_toon_no=50 HAVING fk_actor_no=actor_no;
The kicker is that I also want to have a variable $new_toon_id as the = for the WHERE statement, so, something like: (but only displaying the row as I will eventually plug this into a table and know how to do that fine)
WHERE fk_toon_no=$new_toon_id
fk_actor_no is the foreign key of the cartoon_characters table to the primary key actor_no in the characters table.
I'm trying to get it so that I can print out every character associated with a particular cartoon so it would look something like
(toon id) (character id #) (character name)
($fk_toon_no) (actor_no) (actor)
3 5 Eisenhower
3 9 Nixon
3 12 Uncle Sam
Any help would be greatly appreciated. I think I've included all the relevant information but if I forgot anything please ask.
I'm in desperate need of help. Thanks!!

$query=<<<HERE
SELECT fk_toon_no, fk_actor_no, actor_no, actor FROM cartoon_characters,
characters WHERE fk_toon_no='50' HAVING fk_actor_no=actor_no;
HERE;
$send=mysql_qyery($query);
while($row = mysql_fetch_assoc($send))
{
echo $row["fk_toon_no"];
echo "<br />"
echo $row[fk_actor_no];
}
This should do the trick.

Basic php - echo mysql, how?

I want it to echo how many posts there are in bestallt where its ID is 1 from the table order and display it as how many posts there are in numbers. I am connected to the database in the PHP file, that's not an issue. I'm just not sure how to put it all down in PHP, quite new to this. I just can't get it to echo what I want, nothing comes out/I get an error.
Any help is appreciated!
Your present code does not fetch the data from the database, it simply echoes the SQL query you have written.
Quite a lot more code goes in to fetching results from a mysql database, and I am not sure reproducing a full explanation here will serve anyone's interests. However, you may wish to view the examples of how to use PDO (a method of using mysql databases from php) here, and then either edit or re-ask your question if you find you have specific difficulties following those examples.
Try this code:
<td>
<?php
$sql = "SELECT count(*) FROM order WHERE bestallt='1'"; // Your SQL query
$response = mysql_query($sql);
if (mysql_num_rows($response) == 0) {
// Your query returned 0 rows!
}
while($row = mysql_fetch_array($response)){
// For each row returned from your query
// $row is an array
// For example, You can use it:
echo $row['data1'];
echo $row['data2'];
echo $row['data3'];
// data1, data2, data3 are the name of the fiels in your database
}
?>
</td>
Have a nice day!
Try this,
$sql = "SELECT count(*) FROM order WHERE bestallt='1'"
$res=mysql_query($sql);
$arr=mysql_fetch_array($res);
echo "<pre>";print_r($arr); //you will get whole array for matching record of your order table if found anything

MySQL COUNT showing it's working out

I would expect the following to output the number "5", since there are 5 rows in the database with with item 68 and user 1. But instead I'm getting this output "12345".
$resultb4 = mysql_query("SELECT COUNT(comparedRating) FROM recComparedRating WHERE user1='1' AND itemID='68' GROUP BY itemID AND user1");
while($rowb4 = mysql_fetch_array($resultb4)){
$countcomparedratings=$rowb4['COUNT(comparedRating)'];
}
echo $countcomparedratings;
What am I doing wrong?
The reason you are getting 12345 is because your query is returning 5 results and your code to output the count is simply outputting the concatenation of the returned array from the query.
Without understanding your database structure, I'm guessing that the reason you're getting the '12345' has something to do with your GROUP BY clause. Use a program like MySQLWOrkbench to connect to your database and test out your query before you include it into your code. It is a time saving technique to debug your queries.
Also, I would alias the COUNT value so that you simply refer to the alias when you refer to your column names.
SELECT COUNT(comparedRating) as ratingCount FROM recComparedRating WHERE user1='1' AND itemID='68' GROUP BY itemID AND user1");

mysql query does not work on different files -php

i might be doing some idiot mistake, but i could not figure that out. i have some values coming from html and wanna insert into mysql db. problem is, the very same query does not work in regular php file (that includes other queries), but when i try on an independent php file, it does. here is a sample of the code:
$sql15="insert into body
(Article_ID, Article_Title)
values
('$article_id', '".$_POST['Article_Title']."') ";
mysql_query($sql15);
as i mentioned, the very same code works when i just copy this snippet to a new php file, and it works smoothly.. as you see, there are 20+ insert with the same php, because there are 25+ tables, but data is not much. first 14 query and following 7 queries do work by the way.
do you have any ideas?
There are some things to check and do.
Sanitize user input:
"('$article_id', '".mysql_real_escape_string($_POST['Article_Title'])."')";
You might also want to check if the value is what you expect.
Is your $article_id correct for column Article_ID?
Are your table and column names correct?
Check for errors:
$res = mysql_query($sql15);
if (!$res)
echo mysql_errno($link) . ": " . mysql_error($link);
Show us you complete query:
echo $sql15;
First of all i would suggest you to write your insert query like below
$sql15="insert into body SET Article_ID = '$article_id', Article_Title = '".$_POST['Article_Title']."'";
echo $sql15;
mysql_query($sql15);
so that each time when you add new column to database it would be easy for u to change insert query. echo your query and see it in browser. in it seems to o.k then copy it and paste it in SQL section under your phpmyadmin (see you are choosing proper database) and run it. if one row inserted successfully then your query is alright.
I hope this would help you a little.
$sql15="insert into body
(Article_ID, Article_Title)
values
('$article_id', '".$_POST['Article_Title']."') ";
mysql_query($sql15) or die(mysql_error());
use like this u will be get the error. then u will be find the issue
I think using mysql_real_escape_string may solve your problem.I also recommend you to store your form data in a string.
$article_title= mysql_real_escape_string($_POST['Article_Title']);
$sql15="insert into body
(Article_ID, Article_Title)
values
('$article_id', '$article_title') ";
mysql_query($sql15) or die(mysql_error());

how to updated the keywords from database

hi i have stored 1000 keywords in my database . if i search any keyword(with in my database) my site title must come Like a AIRPORT NETWORKS this title i want . this is for search engine box. how can i do with sql queries i used that below query for displayed my site title.
$ConvertedResultArray = explode('<div id="resultsDiv">', $ConvertedResult);
$V1 = $ConvertedResultArray[0];
$V2 = $ConvertedResultArray[1];
$SponsoredContent = '';
if(strtolower($SearchQuery) == 'taxi')
{
$SponsoredContent = '<br />AIRPORTS<br />NETWORKS';
}
$ConvertedResult = "$V1$SponsoredContent$V2";
i have a only one table named keywords
if i entered that key "taxi" in search box That title comes infront of the page AIRPORTNETWORKS as like that if i entered in the whole 1000 words which it is stored in database it must be come .
how can i do that what sql query i have to use.is it possible. please help me if any one have an idea thanks in advance
I realise this not the answer, but here is something to get you started
SELECT *
FROM Keywords
WHERE Name LIKE "%AIRPORT%"
You need to use AJAX for that. I guess you are speaking about auto complete. if is tat you are talking about do the following steps.
1. use the query given by PerformanceDBA
2. update the textbox value with the first row of query result by triggering textbox onkeyup() event.
If this is not what you want please rephrase your question so tat others can understand..

only retrieving 1 row of data from MYSQL database

I am trying to input multiple pieces of data through a form and all the data will be separated by (,). I plan to use this data to find the corresponding id for further processing through an sql query.
Below is the code I use.
$key_code = explode(",", $keyword);
//$key_count = count($key_code);
$list = "'". implode("','", $key_code) ."'";
//$row_count = '';
$sql4= "SELECT key_id FROM keyword WHERE key_code IN (".$list.")";
if(!$result4 = mysql_query($sql4, $connect)) {
mysql_close($connect);
$error = true;
}else{
//$i = 0;
while($row = mysql_fetch_array($result4)) {
$keyword_id[] = $row['key_id'];
//$i++;
}
//return $keyword_id;
}
The problem i see is that keyword_id[0] is the only element that contains any data (the data is accurate). Even if I input multiple values through the aforementioned form.
I thought it might be an error in the sql but I echo'ed it and it looks like:
SELECT key_id FROM keyword WHERE key_code IN ('WED','WATER','WASTE')
The values in the brackets are exactly what I inputted.
I even tried to figure out how many rows are being returned by the query and it shows only 1. I assume something is wrong with my query but I cannot figure where.
Any help will be greatly appreciated.
Edit: Alright Solved the problem. Thanks to suggestions made I copied and pasted the $sql_query I had echo'ed on the website into mysql console; which resulted in only 1 row being retrieved. After taking a closer look I realized that there was a whitespace between ' and the second word. I believe the problem starts when I input the key_code as:
WED, WATER, WASTE
Instead inputting it as
WED,WATER,WASTE
fixes the problem. I think I should make it so that it works both ways though.
Anyway, thank you for the help.
I am pretty sure that the query is ok. How many rows do you get with just
SELECT key_id FROM keyword
I think that there is just one line that matches your WHERE.
Check the query directly in the database(with phpmyadmin, or in the mysql console), however this query seems to be working as you may assumed. If it returns only 1 row when you use it directly in the db, then maybe there is only one row in your table wich matches this query.
