PHP - Getting Text From Mysql Putting It In Webpage

Hello everyone,

Sorry if this has been answered but if it has I can't find it anywhere. So, from the begining then.  Lets say I had a member table and in it I wanted to store what their top 3 interests are.  Their$ row has all the usual things to identify them userID and password etc.. and I had a further 3 columns which were labled top3_1 top3_2 & top3_3 to put each of their interests in from a post form.

If instead I wanted to store this data as a PHP Array instead (using 1 column instead of 3) is there a way to store it as readable data when you open the PHPmyadmin?

At the moment all it says is array and when I call it back to the browser (say on a page where they could review and update their interests) it displays 'a' as top3_01 'r' as top3_02 and 'r' as top3_03 (in each putting what would be 'array' as it appears in the table if there were 5 results. Does anyone know what I mean?

For example -

If we had a form which collected the top 3 interests to put in a table called users,

Code: [Select]
<form action="back_to_same_page_for_processing.php" method="post" enctype="multipart/form-data">
   
    <input name="top3_01" type="text" value="enter interest number 1 here" />
    <input name="top3_02" type="text" value="enter interest number 2 here" />
    <input name="top3_03" type="text" value="enter interest number 3 here" />
    <input type="submit" name="update_button" value=" Save and Update! " />

   
    </form> // If my quick code example for this form is not correct dont worry its not the point im getting at :)
And they put 'bowling' in top3_01, 'running' in top3_02 and 'diving' in top3_03 and we catch that on the same page with some PHP at the top -->

Code: [Select]
        if (isset($_POST)['update_button']) {
   
    $top3_01 = $_POST['top3_01']; // i.e, 'bowling' changing POST vars to local vars
    $top3_02 = $_POST['top3_02']; // i.e, 'running'
    $top3_03 = $_POST['top3_03']; // i.e, 'diving'

With me so far? If I had a table which had 3 columns (1 for each interest) I could put something like -

  Code: [Select]
   include('connect_msql.php');
   
    mysql_query("Select * FROM users WHERE id='$id' AND blah blah blah");
   
    mysql_query("UPDATE users SET top3_01='$top3_01', top3_02='$top3_02', top3_03='$top3_03' WHERE id='$id'");


And hopefully if ive got it right, it will put them each in their own little column. Easy enough huh? But heres the thing, I want to put all these into an array to be stored in the 1 column (say called 'top3') and whats more have them clearly readable in PHPmyadmin and editable from there yet still be able to be called back an rendered on page when requested.

Continuing the example then, assuming ive changed the table for the 'top3' column instead of individual colums,  I could put something like this -


Code: [Select]
            if (isset($_POST)['update_button']) {
       
        $top3_01 = $_POST['top3_01']; // i.e, 'bowling' changing POST vars to local vars
        $top3_02 = $_POST['top3_02']; // i.e, 'running'
        $top3_03 = $_POST['top3_03']; // i.e, 'diving'
   
    $top3_array = array($top3_01,$top3_02,$top3_03);
   
    include('connect_msql.php');
   
    mysql_query("UPDATE members SET top3='$top3_array' WHERE id='$id' AND blah blah blah");
But it will appear in the column as 'Array' and when its called for using a query it will render the literal string. a r r in each field instead.  Now I know you can use the 'serialize()' & 'unserialize()' funtcions but it makes the entry in the database practically unreadable. Is there a way to make it readable and editable without having to create a content management system?

If so please let me know and I'll be your friend forever, lol, ok maybe not but I'd really appreciate the help anyways.  The other thing is, If you can do this or something like it, how am I to add entries to that array to go back into the data base?

I hope ive explained myself enough here, but if not say so and I'll have another go.  Thanks very much people,  L-PLate (P.s if I sort this out on my own ill post it all here)

Hi,

I am still learning php and I've been racking my brain to get some field data
from the mysql database and put the results into variables to use.

I need to do a query to get the data from two fields and place them in a variable.

I have this field from a form: $_REQUEST['linkurl']

So i need to check this form field against (tablename, fieldname) alldomain.domain_name

when the match is found I need to store the value of tablename, fieldname) domain.manual_approve into $x_manual_approve

and then check that rows userid field: (tablename, fieldname) alldomain.userid and equals (tablename, fieldname) register.id

the userid and id are matching from two different tables (tables alldomain and register).

When I get that match I need to get (tablename, fieldname) register.username and store the value into $x_username

Thanks much for any help,

Gibs

This is my page for editing a post.

However, whenever this form actually goes through, the query for some reason makes post_text in the database blank with no text in it whatsoever.

I have tried echoing the query to see what it says and it has a perfectly fine query and I can copy/paste it manually to put it into the mysql but I don't get why this isn't adding it.

Hi again, I have a bar chart, standard 3 verticle bars coloured differently, but now i want to put some text on them, say: Bar A, Bar B, Bar C.
Also this text has to be rotated 90 degrees

So here is the code to make the bars, I guess I need to use:
$red = imagecolorallocate($im, 255, 0, 0);
imagestring($im, 5, 50, 50, "Bar A", $red);
In some kind of loop
so:

$text = array(
imagestring($im, 5, 50, 50, "Bar A", $red);
imagestring($im, 5, 50, 50, "Bar B", $red);
imagestring($im, 5, 50, 50, "Bar C", $red);
);

can anyone help?
