recognising return key pressed via ASCII??

madhavr

hi all

I need to be able to recognise that the return key is pressed on input. at the moment it simply displays two squares on return key.

i want to be able to increase a y cordinate for printing to the next line when the presence of the return key is there.

any comments please

thanks

madhavr

can someone modify the below code so that when a return is encountered then the Y coordinate is increased?

ive tried using "\r\n" but am not sure if it works
any spaces that do occur are coming out as square symbols on the printout. i want it to goto the next line by incrementing the y coordinate everytime a space is encountered.


function splitSentence($theWord, $num_words, $x, $y, $handle, $cheque = 0)	{
if (!is_numeric($num_words)){
  echo "this value is supposed to be a number!";
}
//$theWord = "one two three four five six seven eight";

$text = trim($theWord);
$words = explode(" ",$text);

//get the total number of words
$num_elements = count($words);
// echo "the number of words: ".$num_elements."<BR>";

//figure out the total number of sentences to create
//use the modulus operator to check the remainder of the division of words array by the number of words/sentence
if (($num_elements % $num_words)>0){
  //if there are more than an evenly dividable set of numbers

  $tot_sent=(int)(($num_elements / $num_words)+1);
}else{
  //evenly dividable
  $tot_sent=($num_elements / $num_words);
}

//assume from your description that you want to create / fill the sentence array before echoing back to the browser
//fill sentence array

//$yy is a counter
for($yy=0; $yy<$tot_sent; $yy++){

  //change the position of the array pointer to continue with the next words in the array
  if ($yy>0){
    $zz=$num_words*$yy;
  }else{
    $zz=0;
  }


  //loop through the $words array and place into sentence
  for($qq=(0);$qq<$num_words;$qq++){
        // echo $words[$qq];
        //fill the sentence
        $sentence[$yy]=$sentence[$yy].$words[$qq+$zz]." ";
        //echo $sentence[$yy];
  } //end $qq for loop

}  // end $yy for loop

//show the sentences
for ($ii=0; $ii<$tot_sent; $ii++){

   $the_sentence=trim($sentence[$ii]);
  // echo $the_sentence."<br>";

   printer_draw_text($handle, $the_sentence, $x, $y);

   if ($cheque == 0) {
   $y = $y+100; // set the coordinates for the next line
   } else {
   // then cheque must be 1 so increase the gap width for cheque 
    $y = $y+250;
   }


} //close the loop


} // end function

please help if you can

many thanks

some progress has been made but its not totally correct.....

its going to the next line but not after the precise charactor has been found.

function splitSentence($theWord, $num_words, $x, $y, $handle, $cheque = 0)	{
if (!is_numeric($num_words)){
  echo "this value is supposed to be a number!";
}
//$theWord = "one two three four five six seven eight";

$text = trim($theWord);
$words = explode(" ",$text);

//get the total number of words
$num_elements = count($words);
// echo "the number of words: ".$num_elements."<BR>";

//figure out the total number of sentences to create
//use the modulus operator to check the remainder of the division of words array by the number of words/sentence
if (($num_elements % $num_words)>0){
  //if there are more than an evenly dividable set of numbers

  $tot_sent=(int)(($num_elements / $num_words)+1);
}else{
  //evenly dividable
  $tot_sent=($num_elements / $num_words);
}

//assume from your description that you want to create / fill the sentence array before echoing back to the browser
//fill sentence array

//$yy is a counter
for($yy=0; $yy<$tot_sent; $yy++){

  //change the position of the array pointer to continue with the next words in the array
  if ($yy>0){
    $zz=$num_words*$yy;
  }else{
    $zz=0;
  }


  //loop through the $words array and place into sentence
  for($qq=(0);$qq<$num_words;$qq++){
        // echo $words[$qq];
        //fill the sentence
        $sentence[$yy]=$sentence[$yy].$words[$qq+$zz]." ";
        //echo $sentence[$yy];
  } //end $qq for loop

}  // end $yy for loop

//show the sentences
for ($ii=0; $ii<$tot_sent; $ii++){

   $the_sentence=trim($sentence[$ii]);
  // echo $the_sentence."<br>";
  $return = chr(13).chr(10);
	if (strstr($the_sentence, $return)) {
	printer_draw_text($handle, $the_sentence, $x, $y);
	$y = $y+100;
	} else {  
   printer_draw_text($handle, $the_sentence, $x, $y);
   } // end if 

   if ($cheque == 0) {
   $y = $y+100; // set the coordinates for the next line
   } else {
   // then cheque must be 1 so increase the gap width for cheque 
    $y = $y+250;
   }


} //close the loop


} // end function

i don't know where u see the [] things, but if u saw it on the browser while testing ur script... probably u are using others
language encoding.

try check
if use IE see whether is like below.
