Combining Arrays

[chriso0258]

I have three arrays:
first_name
last-name
rating.

After a user completes a form, the form sends an email with all the array information. For example, if someone signs up 3 names (it could be 1 to x number of names), the email would look something like this (the names are made up so if your name is one of them, it's just a coincidence 🙂.

Anne, David, Joseph
Smith, Jones, Letterman
860, 250, 1500

What can I do to combine the arrays so that the information in first_name[0] gets connected to last_name[0] to rating[0] so that the email sends the information in this format:

Anne Smith 860
David Jones 250
Joseph Letterman 1500

I'm guessing I would have to process these array into a new array and then have the email use the new array. However, I've looked at various php array functions and can't seem to find one that combines arrays the way I've described.

Any suggestions?

Thank you.

I would just put each person into his own array, and have that array stored in a "people" array:

//Your master array
$people = array();

//Do this for each name they sign up with
$people[] = array('fname' => 'Anne',
                'lname' => 'Smith',
                'rating' => 860);


//When you need to output it
foreach($people as $person)
{
    echo "First Name: ".$person['fname']."\n
        Last Name: ".$person['lname']."\n
        Email: ".$person['email'];
}

Thanks for your replies. Bonesnap, I'm not sure if what you say is possible up front. My form creates the array as follows:

    <INPUT type="button" value="Add Member" onclick="addRow('dataTable')" />

<INPUT type="button" value="Delete Member" onclick="deleteRow('dataTable')" />

<TABLE id="dataTable" width="650px" cellspacing=5>
    <TH>
    <TD>&nbsp; </TD>
    <TD>First Name </TD>
    <TD>Last Name </TD>
    <TD>Chess Rating </TD>
    </TH>
    <TR>
        <TD><INPUT type="checkbox" name="chk"/></TD>
        <TD>&nbsp; </TD>
        <TD> <INPUT type="text" name="first_name[]"/> </TD>
        <TD> <INPUT type="text" name="last_name[]" /> </TD>
        <TD> <input type="number" name="rating[]"/> </TD>
    </TR>
</TABLE>

The idea is that if there is more than one person in a family signing up, they will press a button to add another row. I am using javascript to add the other row. Thus, each array gets added to as more rows are added. In effect, I'm processing the arrays after the form is submitted. So, I'm not sure how to do what you are suggesting since the data is already in an array. Sorry if I sound stupid on this. It's 10pm here and I think I'm going to go to bed.

An old song sung by Sonny and Chere went, "I can see clearly now the rain is gone..."

In my case, after a good night sleep, "I can see clearly now the fog is gone...."

Your right. I didn't think about putting the initial data in an array up front. Thank you very much for your insight and patience.

I used your advice and have created the input array as seen here:

<TABLE id="dataTable" width="650px" cellspacing=5>
  <TH>
    <TD>&nbsp; </TD>
    <TD>First Name </TD>
    <TD>Last Name </TD>
    <TD>Chess Rating </TD>
    </TH>
  <TR>
    <TD><INPUT type="checkbox" name="chk"/></TD>
    <TD>&nbsp; </TD>
    <TD> <input type="text" name="mbr_info[][first_name]"/></TD>
    <TD> <input type="text" name="mbr_info[][last_name]"/></TD>
    <TD> <input type="text" name="mbr_info[][rating]"/></TD>
  </TR>
</TABLE>

I need to combine these into a singe array in the format of:

first_name last_name rating.

I've tried the following code but am getting this error:

Warning: Invalid argument supplied for foreach() in .../com_chronoforms/form_actions/custom_code/custom_code.php(18) : eval()'d code on line 15

Warning: implode() [function.implode]: Invalid arguments passed in ....com_chronoforms/form_actions/custom_code/custom_code.php(18) : eval()'d code on line 18

Here is the code I'm using:

<?php
$name_and_rating = array();
foreach ($form->data[$mbr_info['first_name']] as $k => $v ) {
  $name_and_rating[] = "{$v} {$form->data[$mbr_info['last_name']][$k]} {$form->data[$mbr_info['rating']][$k]}";
}
$form->data['name_and_rating'] = implode("\n", $name-and_rating);
?>

How should I format this to accomplish getting a single array?

Thanks.

Correction on the code. It should be lines 3 and 7.

Can we see the code where you're assigning the arrays into the "people" or "master" array? Also the code where you're calling the foreach loop?

Thanks for your replies 🙂. It turns out I don't need to jump through that php hoop I described above. I can use the mbr_info array just as it is.

Thanks again.
