Array question?

jazappi

Ok please forgive me my brain is fried, I am sure this is a easy one but I can't seem to find it in the archives.

If I have a form that has a bunch of reapeating fields and I want it to only print how many the user has requested, how I can I do this? For example say the user says he has 7 stores, which I am storing as a variable. I only want to print 7 fields and make a new line at after 5 fields how would I do that?

it has to be some kind of foreach stament that will print a <tr>, <td>, <input field>, </td>, </tr>

NOTE: up to five <td> and <input fields> per line. Then break to a new <tr> if the stores field is greater than 5, or have three lines if greater than 10. And so on.

I would like to do this without a crapton of if statements which is the wrong way of course. Please help!!

Thanks in advance. Any advice would be great, it may spark my brain into working again.

guess the if-way is not so wrong ... it worked for me anyway. try that:

<?php
$fieldCount = 7;
$breakAt = 5;
$rowCount = ceil($fieldCount/$breakAt);
$cellCount = $rowCount * $breakAt;
$isNewLine = true;

echo '<table border="1">';
for($i=1; $i <= $cellCount; $i++)
{
	if($isNewLine)
	{
		echo '<tr>';
		$isNewLine = false;
  }

if($i <= $fieldCount)
	echo '<td><input type="text" name="field['.$i.']"></td>';			
else
	echo '<td>x</td>';

if($i > 0 && $i%$breakAt == 0)
{
	echo '</tr>';
	$isNewLine = true;
}
}
echo '</table>';
?>

... but if somone can do it without an IF i'd like to see that, of course ;-)

<?php
$fieldCount = 7;
$breakAt = 5;

echo "<table border=\"1\"><tr>\n";
for($i=0; $i < $fieldCount; $i++)
{
	if($i%$breakAt != 0){
		echo "<td><input type=\"text\" name=\"field[".$i."]\">\n";  

	}else{
		echo "<tr>";
		echo "<td><input type=\"text\" name=\"field[".$i."]\">\n"; 
	}
 }
echo "</table>";
?>

will print this:
http://62.163.148.188/test.php

a new row every 5 coloumns

stolzyboy

so all you do to make it 7 is change

$breakAt = 5;

$breakAt = 7;

then it will be seven td's for every row

Thanks all- I will give that a try and let you know how it works out.

jazappi

This worked perfect. Thanks again.

@: mhhh... your script outputs a table BUT it's not valid HTML anyway =)

it's missing the closing <tr> element and a valid HTML table should always have the same amount of cells in each row, or at least a colspan attribute.

just to mention ... ;-)

As it happens, the HTML spec says that

The number of columns is equal to the number of columns required by the row with the most columns, including cells that span multiple columns. For any row that has fewer than this number of columns, the end of that row should be padded with empty cells. The "end" of a row depends on the table directionality.

cool... i'll update my internal html spec to 4.01 :rolleyes:

but ... uhm... it will look ugly on internet explorer 2.0 ... hehe, gotcha! =)
