[SOLVED] function checktype is not working?

sayedsohail · August 25, 2007

I am having a problem with this function, i don't know why this is just returning false all the time, even though when there is a file sent through the post.

function checkType() {	
while(list($key,$value) = each($_FILES[images][type])){
	strtolower($value);
	if(!empty($value))
	{
		if($value != "application/pdf")
		{return false;}
		else { return true;}

	}

}

}

if (checkType()==FALSE)
{
$errors[]="Sorry , current format is <b>'.($value).'</b> ,only html or pdf files are allowed.";
}

hi, not sure why do you use loop while..... ?

are you uploading more files than one at a time ?

because you can use simple condition

if($_FILES['file']['type'] == "application/pdf") {
return true;
}else{
return false;
}

hope it helps

sayedsohail · August 25, 2007

yes i am uploading more than one file sometimes, i got four file buttons in my email form incase if user wish to submit more than one file at a time.

xpace · August 25, 2007

in that case can you post more of the code, the actual processing of files and/or form for uploading files ?

especially part with variables $key and $value

I added a form, which i assume your using..

this should work fine

<form method="post" enctype="multipart/form-data" >
<input name="images[]" type="file" /><br />
<input name="images[]" type="file" /><br />
<input name="images[]" type="file" /><br />
<input name="submit" type="submit" value="sumit" />
</form>
<?php
function checkType()
{
foreach($_FILES['images']['type'] as $theType)
{
	$value = strtolower($theType);
	if(!empty($value))
	{
		if($value != "application/pdf")
		{
			return false;
		}else{
			return true;
		}
	}
}
}

if (checkType()===FALSE)
{
$errors[]="Sorry , current format is <b>'.($value).'</b> ,only html or pdf files are allowed.";
}else{
echo "WooHoo";
}

sayedsohail · August 25, 2007

you are right, its working, but i would like raise an error if no files are empty or just display a information to the user that, the "email is submitted without any attachments".

MadTechie · August 25, 2007

if no files are uploaded it will fail

function checkType()
{
foreach($_FILES['images']['type'] as $theType)
{
	$value = strtolower($theType);
	if(!empty($value))
	{
		if($value != "application/pdf")
		{
			return false;
		}
	}
}
return true;//or false if they must upload
}

thanks madtechie,

It worked for me in IE, but for some strange reason the latest firefox is giving this error.

Sorry , current format is (application/octet-stream) ,only html or pdf files are allowed?

Does it has to do something WITH pdf filenames, i.e., my file name is 2007-08-08CAT-Q12345ABCDEFGHIJK10.pdf

<?$errors = array();
?>
<form method="post" enctype="multipart/form-data" >
<input name="images[]" type="file" /><br />
<input name="images[]" type="file" /><br />
<input name="images[]" type="file" /><br />
<input name="submit" type="submit" value="sumit" />
</form>
<?php
function checkType()
{
foreach($_FILES['images']['type'] as $theType)
{
	$value = strtolower($theType);
	if(!empty($value))
	{
		if($value != "application/pdf")
		{
			return false;
		}else{
			return true;
		}
	}
}
}

if (checkType()===FALSE)
{
$errors[]="Sorry , current format is <b>($value)</b> ,only pdf files are allowed.";
}else{
echo "WooHoo";
}

MadTechie · August 25, 2007

that code should work fine for both IE & FF,

Use this code in its own file and let me know if you get the same error.

if no files are uploaded it will fail

function checkType()
{
foreach($_FILES['images']['type'] as $theType)
{
	$value = strtolower($theType);
	if(!empty($value))
	{
		if($value != "application/pdf")
		{
			return false;
		}
	}
}
return true;//or false if they must upload
}

Updated

sayedsohail · August 25, 2007

still the same for FF?

MadTechie · August 25, 2007

i just tested this is FF 2.0.0.6, no errors

<form method="post" enctype="multipart/form-data" >
<input name="images[]" type="file" /><br />
<input name="images[]" type="file" /><br />
<input name="images[]" type="file" /><br />
<input name="submit" type="submit" value="sumit" />
</form>
<?php
function checkType()
{
if( isset($_FILES) ) return true;
foreach($_FILES['images']['type'] as $theType)
{
	$value = strtolower($theType);
	if(!empty($value))
	{
		if($value != "application/pdf")
		{
			return false;
		}
	}
}
return true;
}

if (checkType()===FALSE)
{
$errors[]="Sorry , current format is <b>'.($value).'</b> ,only html or pdf files are allowed.";
}else{
echo "WooHoo";
}


?>

sayedsohail · August 25, 2007

sayedsohail · August 26, 2007

it seems its working on your site, here is the code i used iframe to display errors.

form.php

<?
session_start();

?>
<!doctype html public "-//w3c//dtd html 3.2//en">
<?php
echo "<html><head><title>Email Form</title></head>";
$max_no_img=4;  // Maximum number of images value to be set here
echo "<form method='post' action='confirmation.php' enctype='multipart/form-data' target='errorframe'>";
echo "<table class='test' width='100%'>";
echo "<tr height='25px' align='center'><th class ='overState' colspan='4'><font face='verdana' size='2' color='navy' >Email pdf</font></th></tr>
</table>

<table class='test'>
<tr><td>To: </td><td><input type='text' name='to' value='' /></td>
<td>CC: </td><td><input type='text' name='cc' value='' /></td></tr>

<tr><td>BC: </td><td><input type='text' name='bc' value='' /></td>

<td>From: </td><td><input type='text' name='from' value='[email protected]' /></td></tr>

<tr><td>Subject: </td><td colspan='3'><input type='text' name='subject' value='pdf Attached' /></td></tr>
<tr><td>Message:</td><td colspan='3'> </td></tr>
<tr><td> </td><td colspan='3'><textarea cols='60' rows='7' name='message' value=''></textarea></td></tr>";

for($i=1; $i<=$max_no_img; $i++){
echo "<tr><td>Files $i</td colspan='3'><td>
<input type='file' id='pdfs[]' name='pdfs[]' value='' class='formbutton'></td></tr>";
}
echo "<br><TR>
<td align='right' colspan='2'>
<input class='formbutton' type='submit' name ='submit' value='Send' ></td>
<td align='left' align='left' colspan='2'><input class='formbutton' name='exit' type='button' id='exit' onclick='self.close();' value='Close' ></td>
</tr>";

echo "</table></form>";
<table width='100%'><tr><Td><iframe id='errorframe' name='errorframe' style='border:0px;'></iframe></td></tr></table>
</body>

</html>";
?>

Here is the confirmation.php

function checkType()
{

foreach($_FILES['pdfs']['type'] as $theType)
{
	$value = strtolower($theType);
	if(!empty($value))
	{
		if($value != "application/pdf")
		{
			return false;
		}
	}
}
return true;//or false if they must upload
}

if (checkType()==FALSE)
{
$errors[]="Sorry , current format is <b>($value)</b> ,only pdf files are allowed.";
}else{
$errors[]="WooHoo format is OK";
} 

....foreach($errors as $err).... to display errors.

MadTechie · August 26, 2007

change

for($i=1; $i<=$max_no_img; $i++){
echo "<tr><td>Files $i</td colspan='3'><td>
<input type='file' id='pdfs[]' name='pdfs[]' value='' class='formbutton'></td></tr>";
}

to

for($i=1; $i<=$max_no_img; $i++){
echo "<tr><td>Files $i</td colspan='3'><td>
<input type='file' name='pdfs[]' value='' class='formbutton'></td></tr>";
}

it should be fine

sayedsohail · August 26, 2007

Changed but still the the same error, even after downloading a pdf (www.irs.gov/pub/irs-pdf/fw4.pdf) for test purpose from internet. Also updated the firefox just know.

Million thanks madtechie, but i can't cope this anymore, its really making me mad and it 3:20am over here, i am just giving it up now until this afternoon.

But million thanks for your help. I was able to fix the function routines, which is working fine in IE.

MadTechie · August 26, 2007

you from the UK as well (being 3:20am too)

sayedsohail · August 26, 2007

indeed - the last bit i am trying to do is to install acrobat reader and see if it make any difference.

sayedsohail · August 26, 2007

For some strange reason, as soon as i installed the acrobat reader, the functions started behaving normal in ff. atleast i don't have to worry for this weekend.

MadTechie · August 26, 2007

Humm, if you goto Options -> contents -> filetype (Manage button) i think that controls the mime
