Which code snipplets in PHP can create a input form, which creates a new set of data in my mysql database?_问答_开发者

I am using the Google Maps API with parts in javascript and others in PHP.

(I suppose the php will be called by

GDownloadUrl("phpsqlajax_genxml.php", function(data) {
...

in the javascript part of the sourcecode of phpsqlajax_map.htm)

Now I need another php file and the code snipplets for it, which creates an input form where I can add some new locations to the google map. Following code is used to create the xml file here: http://detektors.de/maptest/phpsqlajax_genxml.php The next step would be, trying to make an plugin for wordpress that I could easily post a blog entry with a new location on the same map, which displays already some other locations stored in the mysql database.

thanks!

<?php
require("phpsqlajax_dbinfo.php");

function parseToXML($htmlStr) 
{ 
$xmlStr=str_replace('<','&lt;',$htmlStr); 
$xmlStr=str_replace('>','&gt;',$xmlStr); 
$xmlStr=str_replace('"','&quot;',$xmlStr); 
$xmlStr=str_replace("'",'&#39;',$xmlStr); 
$xmlStr=str_replace("&",'&amp;',$xmlStr); 
return $xmlStr; 
} 

// Opens a connection to a MySQL server
$connection=mysql_connect ($host, $username, $password);
if (!$connection) {
  die('Not connected : ' . mysql_error());
}

// Set the active MySQL database
$db_selected = mysql_select_db($database, $connection);
if (!$db_selected) {
  die ('Can\'t use db : ' . mysql_error());
}

// Select all the rows in the markers table
$query = "SELECT * FROM markers WHERE 1";
$result = mysql_query($query);
if (!$result) {
  die('Invalid query: ' . mysql_error());
}

header("Content-type: text/xml");

// Start XML file, echo parent node
echo '<markers>';

// Iterate through the rows, printing XML nodes for each
while ($row = @mysql_fetch_assoc($result)){
  // ADD TO XML DOCUMENT NODE
  echo '<marker ';
  echo 'name="' . parseToXML($row['name']) . '" ';
  echo 'address="' . parseToXML($row['address']) . '" ';
  echo 'lat="' . $row['lat'] . '" ';
  echo 'lng="' . $row['lng'] . '" ';
  echo 'type="' . $row['type'] . '" ';
  echo '/>';
}

// End XML file
echo '</markers>';

Now I need another php file and the code snipplets for it, which creates an input form where I can add some new locations to the google map.

See: HTML FORMS

See: PHP $_POST

See: SQL INSERT INTO

most of your PHP code is going to be displaying the input form, handling the input form, and connecting to the database and performing an insert query.

[edit===start]

$query = "SELECT * FROM markers WHERE 1";

This is going to present a problem.. what is 1? you might want to compare with specific fields in the database. (markers)

while ($row = @mysql_fetch_assoc($result)){
  // ADD TO XML DOCUMENT NODE
  echo '<marker ';
  echo 'name="' . parseToXML($row['name']) . '" ';
  echo 'address="' . parseToXML($row['address']) . '" ';
  echo 'lat="' . $row['lat'] . '" ';
  echo 'lng="' . $row['lng'] . '" ';
  echo 'type="' . $row['type'] . '" ';
  echo '/>';
  }

@mysql_fetch_assoc should be mysql_fetch_assoc , I think syntax error.

Also, if you want to echo to file not console, change all echo to $file_output.= after $file_output=''; then echo $file_output (or file.. better yet return $file_output; ;))

Of course setting headers and not calling the loop as a function works a bit differently...
