The Problem
Hello, I am creating a search function that will allow users to search for a specific E-Number and see whether it is derived from animals or not. Firstly, I want to dump all the results on the webpage to see if it is 100% correct. I have successflly connected to the database using PHP on my website but the pg_query is not displaying any results, is there more code I need?
The Code
<?php
$conn = pg_connect("***** port=*****
dbname=***** user=***** password=*****");
$res = pg_query($conn, "SELECT * FROM enumbers");
$connection = pg_connect ("host=***** port=*****
dbname=***** user=***** password=*****");
if($connection) {
echo 'connected';
} else {
echo 'there has been an error connecting';
}
?>
Thanks to @LaurenzAlbe for directing me to an answer, I thought I would show it here:
<?php
// Connecting, selecting database
$dbconn = pg_connect("host=***** port=*****
dbname=***** user=***** password=*****")
or die('Could not connect: ' . pg_last_error());
// Performing SQL query
$query = 'SELECT * FROM enumbers';
$result = pg_query($query) or die('Query failed: ' . pg_last_error());
// Printing results in HTML
echo "<table>\n";
while ($line = pg_fetch_array($result, null, PGSQL_ASSOC)) {
echo "\t<tr>\n";
foreach ($line as $col_value) {
echo "\t\t<td>$col_value</td>\n";
}
echo "\t</tr>\n";
}
echo "</table>\n";
?>
As you can see by the code above, I completely forgot about actually printng the results in HTML, this is the reason nothing was showing up.
