PHP - String Build ....

Hello again, guys!

I'm trying to do this:

Get $user_ID -> SELECT FROM favorites WHERE user="$user_ID" -> Now I should create an array with the ID of all the results of the previous command ->
SELECT FROM books WHERE genre="$favorites_ID" -> populate a html table.

The part I've no idea about how to do is building an array with the results and then using the SELECT command, find in the other tables the match.

Could you please give me a hand - one more time?

Is it overkill to use PHP/MySQL to query my database, retrieve the universe of Questions, and then dynamically build a Form?

I have a "Q&A Form" with a whopping 10 Questions.

I suppose dynamically building the Form has the advantage that I always have the most up-to-date Questions and Question Text, but them again, if there is a database issue, I have a larger issue...

Thoughts?

Hiya peeps!

I can't seem to build a preg_match pattern that works.

This is what I need to do.

"[" . $errorID . "]='HERE IS WHAT I NEED TO DISPLAY';"

Does anyone have any ideas on how I would build this regex string?

Many thanks,

James.

OK here is what I have going on right now. Currently I'm trying to build a excel spread sheet into a dynamic form via php. The results are basically questions and are stored each week so for one section they may be asking how many visitors, employee's , etc.. now some of these values that are being entered are going to be used in another question per-say but the result may come from other values that were already submitted so these questions would not be shown in the form that needs to be made later on. The form I'm having trouble with is the initial form to help generate the formula's for these different questions. So what I was going to start doing was have it list all the questions with a check box next to the question if the formula for said question was something like add these two questions and the divide by this set of questions or a whole number then it would display a list of questions for adding together and the get the total from that set and then do a expression afterwards like adding, subtracting, multiplying or dividing. So I was thinking I should list like a set of buttons I think in the beginning. What is the first task at hand Totaling, Adding, Subtracting, Dividing, Multiplying and then when they click on this it would refresh the page and bring up a box that lists all the different questions for them. Then saving the values as which ever button they clicked and once they do this. Then they could either click on say a more button which would pass the values as a array back to the page and continue on or they could click submit and pass the values into a db field as a formula but this is my first concept and would like to know if there may be a better way of doing it.

Ok so I'll try to explain what I'm trying to do the best I can. I want to build an array that allows me to add/remove/modify the variables used at any point in time without having to rebuild or rewrite a ton of new code.

For example, below is an example list of variables I'd like to use in the array, followed by the code I would like to be automatically repeated.

Example Variables: $materialName1, $materialName2, $materialName3, $materialName4, $materialName5, $materialName6 etc etc etc
Example Code to repeat:
Code: [Select]
echo "<tr><td>Material: $materialName1</td><td>Rate: $materialName1Rate</td><td>Weight: $materialName1Weight</td></tr>";

Hopefully that makes sense. As always, very appreciated.

So, I need to build a table based on this table:
Code: [Select]
create temporary table downline (
depth int,
member_id int,
full_name varchar(50),
level int,
referrer_id int,
country char(2)
);
I need to make a table to show each members downline (the people they referred to the site), it needs to be unlimited levels deep, and we have some members that have 25+ levels in their downline, where level 20 has 15,000+ people.

Level 1 = your downline
Level 2 = your donwline's downline
Level 3 = your downline's downline's downline
ect.

I have this loop (after the temp table is built) which needs to build a table on the page.


So, I can not get this table display right for the members downline, any suggestions?

// Build the current users downline and add it to the temporary table
$downline = mysql_query("select * from downline order by depth");
while($row = mysql_fetch_assoc($downline)){

if($row['depth'] != $depth){

$depth_id = $row['depth'];

$content .= "<tr id='main_lvl_$depth_id' class='hiddenInfo' onclick='showHide(this);'><td style='text-align: center;color:#4d53c1;font-weight: bold;' class='w_border'><span class='signs_s'>".$this->dict['mLevels_Level']." $depth_id : </span><span class='signs'>".count($down)." ".$this->dict['mLevels_Members']." </span></td></tr><tr id='lvl_$depth_id' style='display:none;'><td class='w_border' style='text-align: center;'><table style='width:100%;'>";

$i = 0;

$content .= "<tr>

<th>Member ID (Sponsor ID)</th>

<th>Member Name</th>

<th>Country</th>

<th>Member Level</th>

</tr>";

}

$class = ($i%2) ? 'color1NL' : 'color2NL';

$content .= "<tr id='_{$key}_' class='$class'><td class='width33'><a name='_".$row['member_id']."'></a><a href='?mid={$row['member_id']}'>#{$row['member_id']}</a> (<a href='?mid=".$row['referrer_id']."'>#".$row['referrer_id']."</a>)</td><td class='width33'>".$row['full_name']."</td><td>".$row['country']."</td><td class='width33'>".$row['level']."</td></tr>";

$i++;

if($row['depth'] != $depth){

$content .= "</table></td></tr>";

}

$depth = $row['depth'];
}

The following attachment has a working copy. The reason we don't stay with this is because it doesn't work with members who have large downlines, we run out of memory in php, and this hopefully will solve this problem.

How could I build an interactive text system?
 It should work like this:
 Text is displayed.
 1-3 options (a situational amount of them) to answer displayed.
 Example:
 Are you male?
 Yes
 No

 You choose yes or no and it leads you to another questions based from your previous answer.
 Example: (a follow up to the 1st one)
 So you're male. Do you like cars then?
 Answers.
 And it goes on and on.

 The thing I need help with is the answers. I need to show them based by the previous answer but don't know how, any help?

Hey PF. I'm trying to build some better coding habits, so what tips do you guys have? Of course there are obvious things such as well-commented code, neat structure, etc...

But I'm looking for some more "TECHNICAL" tips that might be unspoken. For example, when is a good time to use a variable, opposed to a constant? I notice that a lot of programmers define their database settings with define(), while others just use a $variable. Is this personal preference or maybe its something I'm missing?

I'm looking for ALL tips. Any information that you have, please share it. It will help make me (And anyone else reading this), a better coder.
Thanks in advance.

and if this is not the proper forum, please move it! =]

Hi,

I am trying to recursively build another array based on the one I get back from our CRM api.  The array I get back looks like this:

Code: [Select]

                        )

                    [label] => All
                    [name] => All
                )

        )

The child categories could be any level deep.  I would like put it in an array something like this:
Code: [Select]
Array
(
    [label] => Cat 1
    [level] => 0
    [children] => Array
        (
            [label] => Sub Cat 1
            [level] => 1
            [children] => Array
                (
                    [label] => Sub Sub Cat 1
                    [level] => 2
                )

        )

)

I have tried so many things but I just can't get it right.  Any assistance would be greatly appreciated.

Thanks

I'm confused how to get the chat object to work with the pushes/pulls, and don't know where I'm going wrong.  Here's the basics of what I need to know without reloading the page: how do I push new data to the server how do I push new data to the client how do I not rebuild the data client has every time   I may need to know more, but that's what I know I need to be able to do so far.

Ok I basically want to build a simple php shopping cart. I already have a database with products and product IDs, and each product page has their product ID associated with it by asking the database for it's ID.

Now how would I go about building a shopping cart? I already researched sessions and cookies and came to the conclusion that a session would be best since not all browsers use cookies or have them turned on.

I how ever don't understand how to use sessions for a shopping cart.

I know the first line the code in my php document has to have session_start();

How do I go about adding values to the session?

I'm having an issue with building a multidimensional array via a for (....)
the array should look like the example
any help would be much, much appreciated
thanks siouxx
   
array   
["username"] = "steve"
   array
      ["item"] = "12345"
      array
         "model" = "some model"
         "quantity" = "36.2"
         "details"
         array
            0 = "detail 1"
            1 = "detail 2"
            2 = "detail 3"

["username"] = "steve"
   array
      ["item"] = "000257"
      array
         "model" = "some other model"

         array
            0 = "detail 1"
            1 = "detail 2"
            2 = "detail 3"
            3 = "detail 3"

the array return by sql looks like this

Hello everyone,

i use content security policy set at self for javascript and css. unsafe-inline is forbidden. However, i want to allow the background to be changed in tow ways: foto selection and color selection if photos are turned off. I have accomplished all of this but unsafe inline does not help my purpose. I need the color to be accessible via css file. Thus, input color cannot be used here unless i dynamically crete a css file based upon a selection. I don't want to do this, so i hardcoded the 216 colors into a css file which is only 6kb. perfect! now i need to loop through the color values to dynamically create the 216 color palette. I've never done this before so i had to think about it and try to recognize a pattern. I noticed that red is first follwed by green and blue. so green and blue should be together inside a red loop. I've tested my theory and it works. yipee. Now i want to know if there is a better method for accomplishing this task? i've tried searching google with no luck at all. i don't know what to search for other than 'build a 256 color palette using php loops'. I really find nothing of value. Amazing!

here is my code which is working. so can someone offer a more professional method?

<?php declare (strict_types = 1);
  $rgb = ['00','33','66','99','cc','ff'];
  $colors = 0;

  foreach ($rgb as $red) {
      foreach ($rgb as $green) {
          foreach ($rgb as $blue) {
              echo $red . $green . $blue . ', '; ++$colors;
          }
      } echo '<br><br>';
  } echo 'there are ' . $colors . ' colors in this palette';

exit;
?>

Thank you very much and i hope that you all have a fantastic day 🙂
