merging two array

[prakash]

I need and idea regarding how to merge two seperate data from the form.

 

The first field form type is "textbox" and second is "file". and the two fields were in an array form like.

 

<form name="myform" method="post" action="action.php">
<input type="text" name="myfield[]"><input type="file" name="myimage[]">
<input type="text" name="myfield[]"><input type="file" name="myimage[]">
<input type="text" name="myfield[]"><input type="file" name="myimage[]">
<input type="text" name="myfield[]"><input type="file" name="myimage[]">
<input type="text" name="myfield[]"><input type="file" name="myimage[]">
</form>

 

so how can I merge and loop two data through php.

I need to use the array value on my script if...else condition.

 

loop {

if (....both array is not blank) {

//do something

print first array;

print second array

}

}

Try this

<?php
foreach($_POST['myfield'] as $K => $V)
{
echo "textBox=$V<br>";
echo "File=".$_FILES[$K]['name']."<br>";
//Add If here 
if( !empty($_FILES[$K]['name']) && !empty($V) )
{
//Both NOT empty
//NOTE: i used $V for the text, i could also do $_POST[$K]['myfield']
}
}
?>

[prakash]

ok I got the idea,

 

in the above example $K is used as indexes and $v for the value.

and the value of FILE is retrieved on each loop via a array indexes i.e. $k

 

am I right?

Why don't you change your form to something like:

<form name="myform" method="post" action="action.php">
<input type="text" name="myinput[1][myfield]"><input type="file" name="myinput[1][myimage]">
<input type="text" name="myinput[2][myfield]"><input type="file" name="myinput[2][myimage]">
<input type="text" name="myinput[3][myfield]"><input type="file" name="myinput[3][myimage]">
<input type="text" name="myinput[4][myfield]"><input type="file" name="myinput[4][myimage]">
<input type="text" name="myinput[5][myfield]"><input type="file" name="myinput[5][myimage]">
</form>

Then you can process it like:

<?php
for ($i=1;$i<6;$i++) {
    if ($_POST[$i]['myfield'] != '' && $_POST[$i]['myimage'] != '') {
//
//          do something
//
    }
?>

 

With your current form definition, there is not a one-to-one correspondence between the array fields. If someone entered some text in the first "myfield" and nothing in the first "myimage" and then put nothing in the second "myfield" and put something in the second "myimage", both would show up as the first entry in the array.

$K = Key (AKA index number)

 

So

as you loop through the post (via the key) you also check the FILES with the same key

 

or use kenrbnsn idea

Try this

<?php
foreach($_POST['myfield'] as $K => $V)
{
echo "textBox=$V<br>";
echo "File=".$_FILES[$K]['name']."<br>";
//Add If here 
if( !empty($_FILES[$K]['name']) && !empty($V) )
{
//Both NOT empty
//NOTE: i used $V for the text, i could also do $_POST[$K]['myfield']
}
}
?>

 

mmm how can $_FILES[$K]['name'] get details for myimage[].

I think it should be $_FILES[$K]['myimage']['name'] or something like that ????

[MadTechie]

Ahhh, your right, kinda missed that (read my signature, i don't test this stuff LOL)

 

$_FILES[$K]['myimage']['name']

looks about right

remember the $K is just the index(key)

 

mmm how can $_FILES[$K]['name'] get details for myimage[].

I think it should be $_FILES[$K]['myimage']['name'] or something like that ????

I got problem. Both the script below is not working for $_FILES

 

<form name="myform" method="post" action="test.php">
<input type="hidden" name="cmd" value="_runscript">
<input type="text" name="myfield[]"><input type="file" name="myimage[]"><br>
<input type="text" name="myfield[]"><input type="file" name="myimage[]"><br>
<input type="text" name="myfield[]"><input type="file" name="myimage[]"><br>
<input type="text" name="myfield[]"><input type="file" name="myimage[]"><br>
<input type="text" name="myfield[]"><input type="file" name="myimage[]"><br><br>
<input type="submit">
</form>
<?php
if ($_POST['cmd']=="_runscript") {
foreach($_POST['myfield'] as $K => $V)
{
echo "textBox=$V<br>";
echo "File=".$_FILES[$K]['myimage']['name']."<br>";
//Add If here 
if( !empty($_FILES[$K]['name']) && !empty($V) )
{
//Both NOT empty
//NOTE: i used $V for the text, i could also do $_POST[$K]['myfield']
}
}
}
?>

 

<form name="myform" method="post" action="test.php">
<input type="hidden" name="cmd" value="_runscript">
<input type="text" name="myfield[]"><input type="file" name="myimage[]"><br>
<input type="text" name="myfield[]"><input type="file" name="myimage[]"><br>
<input type="text" name="myfield[]"><input type="file" name="myimage[]"><br>
<input type="text" name="myfield[]"><input type="file" name="myimage[]"><br>
<input type="text" name="myfield[]"><input type="file" name="myimage[]"><br><br>
<input type="submit">
</form>
<?php
if ($_POST['cmd']=="_runscript") {
foreach($_POST['myfield'] as $K => $V)
{
echo "textBox=$V<br>";
echo "File=".$_FILES[$K]['myimage']['name']."<br>";
//Add If here 
if( !empty($_FILES[$K]['myimage']['name']) && !empty($V) )
{
//Both NOT empty
//NOTE: i used $V for the text, i could also do $_POST[$K]['myfield']
}
}
}
?>

try

$_FILES['myimage'][$K]['name']

instead..

[prakash]

it's not working at all

[prakash]

the following code works

 

$_FILES['myimage']['name'][$K]

[MadTechie]

tested

also note the enctype="multipart/form-data"

<form name="myform" method="post" action="test.php" enctype="multipart/form-data" >
<input type="hidden" name="cmd" value="_runscript">
<input type="text" name="myfield[]"><input type="file" name="myimage[]"><br>
<input type="text" name="myfield[]"><input type="file" name="myimage[]"><br>
<input type="text" name="myfield[]"><input type="file" name="myimage[]"><br>
<input type="text" name="myfield[]"><input type="file" name="myimage[]"><br>
<input type="text" name="myfield[]"><input type="file" name="myimage[]"><br><br>
<input type="submit">
</form>
<?php
print_r($_FILES);
if ($_POST['cmd']=="_runscript") {
foreach($_POST['myfield'] as $K => $V)
{
echo "textBox=$V<br>";
echo "File=".$_FILES['myimage']['name'][$K]."<br>";
//Add If here 
if( !empty($_FILES['myimage']['name'][$K]) && !empty($V) )
{
//Both NOT empty
//NOTE: i used $V for the text, i could also do $_POST[$K]['myfield']
}
}
}
?>
