[SOLVED] is there anything like implode, but vertically?

[jaydeesmalls]

Hi everybody,

 

On one of my pages, I have a form that a user can input data into a series of lines:

 

ex:

1:__line 1__________

2:__line 2__________

3:____________

4:__line 4__________

 

and when the form is submitted, it is echoed in the same fashion

 

ex.

line 1

line 2

 

line 4

 

I am wondering if there is a way to make it so that if a person didn't input anything in one of the lines, the following line would be echoed up a line (sort of like implode, but vertically)?

 

ex.

line 1

line 2

line 4

 

Thanks for the input

Post your current code. Where does the user enter the *lines*? within a textarea?

[jaydeesmalls]

Yes, within a textarea.

 

I'm at work now, and do not have access to the code.  sorry.

 

Basically, the user fills out a form, the info is then processed by another file, and echoed on a third page.

 

Thanks

Uhh...implode() has nothing to do with whether or not it ends up horizontal or vertically...that depends on what you actually implode...Did you try:

 

echo implode("<br />", $list);

 

>_>

I am assuming it'd be something like

 

$string = explode("\n", $var)

[DarkWater]

Nah, you'd need to put an HTML line break.  My code was supposed to read:

 

echo implode('<br />', $list);

[Jabop]

Nah, you'd need to put an HTML line break.  My code was supposed to read:

 

echo implode('<br />', $list);

 

Ah yes, I was thinking the lines of a text file, not the lines of a text BOX.

If you want to remove more that one line you have to look for multiple line breaks then replace with one

 

<?php
$text = $_POST['tarea'];
$array = array("\r\n\r\n", "\n\n", "\r\r");
$replace = "\r\n";
$newtext = str_replace($array, $replace, $text);
echo nl2br($newtext);
?>

I didn't think that he was putting it back into a textbox.  I think he's echoing it straight out.

[jaydeesmalls]

Thanks for all the input.

 

Yes, I'm echoing straight out.

 

I'll try those both when I have the opportunity tonight.  they make sense, I'm certain one of them will work.

 

thanks again

Based on memory, I think my code looks similar to this

(warning, it's not pretty at all)

 

<?php 
$query="SELECT * FROM $tbl_name WHERE id='33'";
$result=mysql_query($query);
while ($row = mysql_fetch_array($result))
{
echo '<h5>', ($row['rem1']), '</h5>';
}
mysql_free_result($result);
?><br />
<?php 
$query="SELECT * FROM $tbl_name WHERE id='34";
$result=mysql_query($query);
while ($row = mysql_fetch_array($result))
{
echo '<h5>', ($row['rem1']), '</h5>';
}
mysql_free_result($result);
?><br />
<?php 
$query="SELECT * FROM $tbl_name WHERE id='35'";
$result=mysql_query($query);
while ($row = mysql_fetch_array($result))
{
echo '<h5>', ($row['rem1']), '</h5>';
}
mysql_free_result($result);
?><br />
<?php 
$query="SELECT * FROM $tbl_name WHERE id='36'";
$result=mysql_query($query);
while ($row = mysql_fetch_array($result))
{
echo '<h5>', ($row['rem1']), '</h5>';
}
mysql_free_result($result);
?><br />

 

What I'm looking for is if someone entered values in 33, 34, and 36, but not 35, it would be echo as:

 

33

34

36

 

not

 

33

34

 

36

 

Thanks

 

[jaydeesmalls]

So I tried the

 

implode('<br />', $list);

 

method and that created more spaces between the lines.

 

ex.

 

33

 

 

 

34

 

 

 

36

 

???????

[jaydeesmalls]

bump for the night time peeps

 

any other suggestions?

[craygo]

problem is you are using a bunch of queries then putting a break in. Why not use 1 query.

 

<?php
$s = array(33,34,35,36);
$values = implode("', '", $s);
$query="SELECT * FROM $tbl_name WHERE id IN ('$values')";
$result=mysql_query($query);
while ($row = mysql_fetch_array($result))
{
echo '<h5>', ($row['rem1']), '</h5>';
}
mysql_free_result($result);
?><br />

Craygo, so I tried what you posted, and everything gets echoed on one line. 

 

ex: 33 34 36

 

Thank you for the input

[craygo]

my bad I forgot <h> tags don't start a new line.

<?php
$s = array(33,34,35,36);
$values = implode("', '", $s);
$query="SELECT * FROM $tbl_name WHERE id IN ('$values')";
$result=mysql_query($query);
while ($row = mysql_fetch_array($result))
{
echo '<h5>', ($row['rem1']), '</h5><br />';
}
mysql_free_result($result);
?>

[jaydeesmalls]

Ray,  thanks again.

 

I tried that and I am still getting blank lines between lines with information

 

ex (if lines 34 and 35 were empty):

33

 

 

36

 

when I am looking for a way so it would echo:

33

36

 

thanks.

BY default header tags (<h1> to <h6>) have a default padding/margin. Because of this your numbers will be spaced apart.

 

To remove padding/margin apply the following CSS

h5 {
 padding: 0;
 margin: 0;
}

 

Or don't use a header tag to display your numbers.

[jaydeesmalls]

Thanks Wildteen.  I don't think I was clear on my previous post.  I apologize for that.

 

When I echo, I am looking to make it similar to how I go this implode statement to work:

$query="SELECT * FROM $tbl_name WHERE id ='10'";
$result=mysql_query($query);
while ($row = mysql_fetch_array($result))
{
$array = array('<h5 class="update1">', ($row['up1']), '</h5>', '<h5 class="update2">', ($row['up2']), '</h5>', '<h5 class="update3">', ($row['up3']), '</h5>');
$comma_separated = implode(" ", $array);
echo $comma_separated;
} 
mysql_free_result($result);
?>

 

In that example, it was echoed on one line, and if there was nothing input in $row['up2'], it would be replaced with a " " and the proceeding input (up3) would be echoed immediately after the initial input (up1).

 

I am looking for a way so that instead of this happening on one horizontal line, it happens with one input per line.

 

Thank you for helping.

[wildteen88]

Does each row have three columns, called upX (X being a number 1 to 3) If so do

$query = "SELECT * FROM $tbl_name WHERE id ='10'";
$result = mysql_query($query);

while ($row = mysql_fetch_array($result))
{
    $i = 1;
    foreach($row as $item)
    {
        if(!empty($item))
        {
            echo '<h5 class="update' . $i .'">' . $item . '</h5>';
        }

        $i++;
    }
}

mysql_free_result($result);

[jaydeesmalls]

Thank you Wildteen and Craygo for all your patience and assistance.  I found out that it was a css issue (display:inline), and the problem is solved.

 

I appreciate all the input.
