foreach - using multiple times - possible?

Catfish

Hi guys/gals,

I am trying to do the following without any success.

I have a form which is generated by values from a db. It pulls first name, last name, time, date, personnel. Well that form looks great. The personnel field is the only populated drop down with all personnel that you can select to handle the situation.

The problem is when I submit the form, I cannot get the data to all print out on the next page. I use this on the form.

<TABLE WIDTH='100%' BORDER='0' CELLSPACING='5' CELLPADDING='0'>
<TR>
<TD WIDTH='25%'>$a $b</TD>
<TD WIDTH='45%'>$date @ $start - $end</TD>
<TD WIDTH='30%'><SELECT NAME='repo'>
<OPTION VALUE='$repo' SELECTED>$repo_name
<OPTION VALUE='name1'>me
<OPTION VALUE='name2'>you
</SELECT></TD>
</TR>
</TABLE><BR>
<INPUT TYPE='hidden' name='a' value='$a'>
<INPUT TYPE='hidden' name='b' value='$b'>
<INPUT TYPE='hidden' name='date' value='$date'>
<INPUT TYPE='hidden' name='start' value='$start'>
<INPUT TYPE='hidden' name='end' value='$end'>
<INPUT TYPE='hidden' name='id[]' value='$id'>

then the next page....

foreach ($a AS $a1) {

echo "<TABLE WIDTH='100%' BORDER='0' CELLSPACING='5' CELLPADDING='0'>
<TR>
<TD WIDTH='25%'>$a $b</TD>
<TD WIDTH='45%'>$date @ $start - $end</TD>
<TD WIDTH='30%'>$repo</TD>
</TR>
</TABLE><BR>";
}

well, this prints out the correct amount of results, except only the $id value is the only variable that is listed as individual results.

How do I get all variables from the form to print out individually on the next page? Thanks and I hope I explained my ignorance well.

Assuming you have register_globals enabled, how can you do a foreach() on $a when $a isn't an array?

Catfish

I posted just 1 example. I have tried the following...

and then my question was....can you add more to a foreach statement other than x as y.....or what is the correct way to do this? Thanks

Shrike

You probably want to foreach() the $POST global as this will contain all of the form data. Also in a foreach you can do:

foreach($_POST as $key => $value){
  echo "$key is the field name<br>$value is the field value";
}

Catfish

Thnaks for replying so timely. I guess I am missing it. What is "foreach() the $_POST global" because when I foreach the 1 field, that field prints 9 individaul results (correct #) but all the other fields I list in my question repeat themselves. Like (date) is the same date 9 times, as well as all other fields but what I specified in foreach()

Any ideas? Thanks again

You probably want to do something like this:

$starts = $_POST['start'];
$ends = $_POST['end'];
for($i = 0; $i < count($starts); $i++) {
  $start = $starts[$i];
  $end = $ends[$i];
  echo $start . ' ' . $end . "<br />\n";
}

Actually, I really didn't understand your original post. I'm assuming all the variables are being submitted as an array. If not then disregard.

Catfish

well, it looks like it makes sense except it does not work. parse error and I am not keen enough to tell you why.

Parse error: parse error, unexpected T_VARIABLE, expecting ',' or ';'

Hi, does anyone know how to pass this info to a new page? When I do a foreach() it only passes the 1 array as single results. The rest of the variables (only the last line of variables) print on the next page. So it already knows there are 2 seperate results since it passes the $ID variable 2 times and it is seperate, but every other variable does not print, just the last row of variables. Any help would be great. Thanks

Catfish

Please? I am really trying to search for answers to no avail.

Shrike

From your example above, you are only passing 1 value for each hidden field. You'd need to do something like

<input type="hidden" name="name[]" value="value1">
<input type="hidden" name="name[]" value="value2">
.... then in PHP ....
foreach($_POST['name'] as $value){
  echo $value."<br>";
}

e.g. each hidden field value you want adding to the array _must_ have the same name attribute, and the square brackets.

Catfish

this is incorrect?

cause when I do

foreach($_POST['name'] as $value){
echo $value."<br>";
}

foreach ($a AS $a1) {

echo "<TABLE WIDTH='100%' BORDER='0' CELLSPACING='5' CELLPADDING='0'>
<TR>
<TD WIDTH='25%'>$a1 $b</TD>
<TD WIDTH='45%'>$date @ $start - $end</TD>
<TD WIDTH='30%'>$repo</TD>
</TR>
</TABLE><BR>";
}

it only echoes the $a1 on the page as an individual result? Well on the previous page, there could be a list of 25 $name's, $id's, etc... so how do I pass all of it.

I am sorry if I am not clear on this, I wish I knew how to better explain it.

Thanks

Shrike

Each hidden field you want added to an array in the $POST global must_ have the same name attribute. I didn't mean 'name' literally but whatever you choose to call it.

Catfish

I know you were just using "name" as an example, but it still does not solve my problem.

Is this the right thing to do?

If so, then how do I get 25 seperate values of $a, 25 seperate values of $b, and so forth for each var above to print as seperate results on the next page.

Because using foreach($a AS $a1){ echo "$a1";} will print me 25 seperate results for $a1, but none of the other vars will print as individual results. Does this make sense?

ahundiak

So you have 25 sets of the input variable right?

If so, please scroll up and look at my previous post. Don't use for each. Just use an index.

Catfish

I stated that example did not work, I got a parse error on the last line of your example and I do not know why. Do you?

ahundiak

Yes. In fact i fixed it. Just missing a . in the echo statement. It's not always possible to test the code being posted to this board. So sometimes little errors can slip in. You will get used to debugging simple stuff.

Catfish

I hope I do get used to it. The last line was all I did not understand once you wrote it out. The whole "." thing is new to me. Thank you so much for the info, it worked like a charm and it really helped me understand arrays and how they function on a base level.

I kept thinking...wouldn't it be nice to do foreach($a AS $a1 && $b AS $b1){} but then that is why I am posting on the noob forum!!! :}

Anyhow, I see the echo of the data and it is perfect and was wondering if you could point me in the right direction to do a mail() with the printed results rather than an echo. I was thinking of using the same count line for the $message body. Do you think that is the right way to accomplish this?

Thanks again, you renewed my spirit in this.
