导出的RTF文档中的记录未循环

I am exporting content from an MySQL database to a Word Template (RTF) via PHP.

There is a section, "Appendix B", which should display all the Acronyms found for a record. The minimum records to appear for this section is 90 (i.e. these are standard acronyms (tblAcronyms) that each record will have); however the maximum records are unknown since users can add to this listing (tblAppendixB).

The Word (i.e. RTF) document should display all the records found, however, it is only displaying the first record.

This is what I have thus far:

<?php
....

#Retrieve Appendix B records
$qry_get_AppB = "SELECT vAcronym, vAcronymDesc FROM tblAcronyms
                   UNION SELECT vAcronym, vAcronymDesc FROM tblAppendixB
                     WHERE fkID = ". $i_fk_id . " ORDER BY vAcronym ASC";
$qry_appb_result = mysql_query($qry_get_AppB);
$qryAppBno_rows = mysql_num_rows($qry_appb_result);    

//Generate the headers to help a browser choose the correct location
header('Content-Type: application/msword');
header('Content-Disposition: inline; filename="'.$vProgramName.'_rec.rtf");

//Open the template file
$tfilename = 'Appb_Template.rtf';
$fp = fopen($tfilename, 'r');

//Read the template into a variable
$toutput = fread($fp, filesize($tfilename));

fclose($fp);

//Replace the place holders in the template with data
if($qryAppBno_rows > 0)
{
  while($rowAppB = mysql_fetch_array($qry_appb_result)) 
  {
     $vAppB = $rowAppB['vAcronym'] . '-' . $rowAppB['vAcronymDesc'] . "
";
     $toutput = str_replace('<<vAppB>>', $vAppB, $toutput);
  }
}

//Send the generated document to the browser
echo $toutput;

?>

I have searched this forum and others but have yet to find a solution.

Any assistance is greatly appreciated.

Okay, I'm not quite sure what your template looks like, but I guess, you only have 1 place holder named <<vAppB>>. In your 1st iteration (if there is any data available) you replace that placeholder with your 1st data entry. In this fact only one placeholder is shown.

May rewrite your code to something similar to this

... //do your stuff
$newLine = "
";
$appendix = "";
while($rowAppB = mysql_fetch_array($qry_appb_result)) {
    $appendix .= $rowAppB['vAcronym'] . '-' . $rowAppB['vAcronymDesc'] . $newLine;
}
$toutput = str_replace('<<vAppB>>', $appendix, $toutput);
...//do some other stuff

Just simple prototyping, so you may have to do some additional work.

The trick is to collect all entries you got and than replace it with your placeholder :)

I resolved the problem; I had to use "\par" instead of " " for MS Word (RTF) to recognize it as a paragraph mark. Here is the modified code that now works:

<?php
....

$t_newline = "\par";

#Retrieve Appendix B records
$qry_get_AppB = "SELECT vAcronym, vAcronymDesc FROM tblAcronyms
               UNION SELECT vAcronym, vAcronymDesc FROM tblAppendixB
                 WHERE fkID = ". $i_fk_id . " ORDER BY vAcronym ASC";
$qry_appb_result = mysql_query($qry_get_AppB);
$qryAppBno_rows = mysql_num_rows($qry_appb_result);    

//Generate the headers to help a browser choose the correct location
header('Content-Type: application/msword');
header('Content-Disposition: inline; filename="'.$vProgramName.'_rec.rtf");

//Open the template file
$tfilename = 'Appb_Template.rtf';
$fp = fopen($tfilename, 'r');

//Read the template into a variable
$toutput = fread($fp, filesize($tfilename));

fclose($fp);

//Replace the place holders in the template with data
if($qryAppBno_rows > 0)
{
   while($rowAppB = mysql_fetch_array($qry_appb_result)) 
   {
       $vAppendixB[] = $rowAppB['vAcronym'] . '-' . $rowAppB['vAcronymDesc'] . $t_newline;
       $vAppB = implode(" ", $vAppendixB);
   }
}

$toutput = str_replace('<<vAppB>>', $vAppB, $toutput);

//Send the generated document to the browser
echo $toutput;

?>

Hopefully this will help someone else. :-)
