Barand's post in How do I get the results to show as a table was marked as the answer
Output the results into an HTML table
Put each result row in a new table <tr> row. Put each column into a table <td> cell.
EG
<?php // CONNECT TO DB HERE $sql = "SELECT animal_type , animal_breed , colour , owner_name , address , telephone , mobile , email , offence , offence_date , offence_location , case_status , case_ref , action_required , action_taken , microchipped , microchip_number , aggressive , dangerous , lost , date_lost , location_lost , stolen , date_stolen , location_stolen , found, date_found , location_found , other_information FROM `animals` -- WHERE 1 (utterly useless, just leave it out) "; //------------------------------------------------------------------------------ // I find this function useful for testing // queries when I haven't got MySql Workbench open function query2HTML($db, $sql) { $output = "<table border='1'>\n"; // Query the database $result = $db->query($sql); if ($result->num_rows == 0) return "No matching records"; // get the first row and display headings $row = $result->fetch_assoc(); $output .= "<tr><th>" . join('</th><th>', array_keys($row)) .

Barand's post in not sure what to do with action equals index.php was marked as the answer
It looks like it expects that code to be in "index.php". The posted data will be sent to that file (itself)
If you remove action="index.php" you can call your php file anything and, without the action, it will call itself.

Barand's post in MYSQLI Object orientated & procedural tutorials was marked as the answer
Your query failed, so $result contains false and not a result object.
Put this code before your call to nysql_connect...
mysqli_report(MYSQLI_REPORT_ERROR|MYSQLI_REPORT_STRICT); ... it won't stop it failing but it will tell you why.

Barand's post in Hi, have a qustion please was marked as the answer
I didn't notice before (because you didn't use a code block) but you have used backticks around `%search_data_value%`. Those will force SQL to treat it as a column name. Use single quotes around strings.
-
Barand's post in Help with Syntax was marked as the answer
Ticks are only used in SQL queries around identifiers.
When using quotes (single or double) they should be in matching opening and closing pairs.
do_check('<a href="\emwin\adm\cwfmob.txt' title="Coastal Water Forecast" target="_self">CWFMOB</a>','\emwin\adm\cwfmob.txt',60*60*60,'\emwin ...'); ^..............................^ ^......................^ ^.....^ ^.^ ^..........^ As you can see, you href does not have matching opening and closing quotes, throwinng other pairs out of synch.
try
do_check('<a href="\emwin\adm\cwfmob.txt" title="Coastal Water Forecast" target="_self">CWFMOB</a>','\emwin\adm\cwfmob.txt',60*60*60,'\emwin ...'); ^.....................^ ^......................^ ^.....^ ^........................................................................................^ ^.....................^ ^..........^

In the above, "=" should be "==".
If you use "=" you assign "" to the variable clearing any value it had.

Barand's post in Query Multiple Tables using 1 common field was marked as the answer
The names do not have to be the same, although it does make relationships clearer if they are. What matters is the value in the columns as that is what is used to match a record in a table to one or more related records records in another table.
Before using a database, the tables in it should be normalized. Looking at your tables, that term is something new to you and your whole design is bad need of repair. The correct design of your data makes life a lot easier further down the road.
There is a link to an SQL tutorial in my signature that may help you.

Since you found that this...

without the "..." to expand the array into a comma separated list?

Barand's post in how to Run a line of code after 10 minutes of running another line of code in PHP was marked as the answer
Here's one way.
When you send a payment confirmation write a record (forename, surname, email) to "confirmation" table
CREATE TABLE `confirmation` ( `confirm_id` int(11) NOT NULL AUTO_INCREMENT, `forename` varchar(45) DEFAULT NULL, `surname` varchar(45) DEFAULT NULL, `email` varchar(45) DEFAULT NULL, `time_confirmed` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP, `tips_sent` datetime DEFAULT NULL, PRIMARY KEY (`confirm_id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; Set up a cron job to run every 5 minutes. This would
SELECT confirm_id, forename, surname, email FROM confirmation WHERE tips_sent IS NULL AND NOW() - INTERVAL 10 MINUTE > time_confirmed; foreach record returned
Send welcome tips email UPDATE confirmation SET tips_sent = NOW() WHERE confirm_id = ? -

Barand's post in there seems to be no difference between CHAR and VARCHAR was marked as the answer
Use varchar for columns which can have values of variable lengths (names, address lines, descriptions, comments etc)
Use char when you have values of fixed length (EG US state abbreviations could be CHAR(2), or if you have a product table that has a 4-character product code then CHAR(4)).
If in doubt use varchar, but don't go mad and make everything VARCHAR(255) as some do. Keep them as sensible size for the expected content. You don't want people entering a phone number with 255 digits just because your DB allows it.

Barand's post in CRUD read. An overview of all the members was marked as the answer
If you are happy to display the multiple numbers and emails as, say, comma-separated lists, then you can use GROUP_CONCAT on those columns and GROUP BY Lidnummer.
SELECT lid.Lidnummer , lid.Naam , lid.Voornaam , lid.Huisnummer , lid.Postcode , postcode.Adres , postcode.Woonplaats , GROUP_CONCAT(telefoonnummers.Telefoonnummer SEPARATOR ', ') as Telefoonnummer , GROUP_CONCAT(email.Emailadres SEPARATOR ', ') as Emailadres FROM lid INNER JOIN postcode ON lid.Postcode = postcode.Postcode INNER JOIN telefoonnummers lid.Lidnummer = telefoonnummers.Lidnummer INNER JOIN email ON lid.Lidnummer = email.Lidnummer GROUP BY lid.Lidnummer; Use explicit joins and not "FROM A, B, C WHERE..."
When posting code in the forum, use the <> button to create a code block and specify the code type.

Barand's post in Syntax issues, still a newbie but getting there! was marked as the answer
HTML code wil not be output when it is inside <?php .. ?> tags. It need to be output using echo command.
<?php if ($ticket['status'] == 'Fermé') { echo "<div class=\"btns\"> <a href='viewtest.php?id={$_GET['id']}&status=Réouvert' class='btn blue' style='width:400px'>Réouvrir ce billet</a> </div> "; echo 'billet fermé'; } ?> The alternative is exit php mode, output the html then re-enter php mode, which gets very messy...
<?php if ($ticket['status'] == 'Fermé') { echo "<div class=\"btns\">"; // I would need this part to echo the button correctly if above status is Fermé ?> <a href="viewtest.php?id=<?=$_GET['id']?>&status=Réouvert" class="btn blue" style="width:400px">Réouvrir ce billet</a> <?php //End of part echo "</div>"; echo 'billet fermé'; } ?>

Barand's post in I can't push my record to mysql database was marked as the answer
Remove the single quotes from around the tablename and column name identifiers. Quotes are for string literals.
$sql="INSERT INTO 'users' ('name','email','phone','bgroup') VALUES ('$name','$email','$phone','$bgroup')"; ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ REMOVE Also, you should use a prepared statement instead of putting user-provided variables into your query.
