php - mysql から画像を保存して取得する方法

Question

私はmysqlでphpを使用しています。

さまざまなフィールドを持つフォームを作成したい。

htmlでのフォームはこんな感じです。

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
<script type="text/javascript">
var categories = [];
categories["startList"] = ["Rental","Sale"]
categories["Rental"] = ["Residential","Commercial"];
categories["Sale"] = ["Commercial","Residential"];
categories["Residential"] = ["Flot","Independent"];
categories["Commercial"] = ["Play & Plug","Baseshare"];
categories["Biography"] = ["Play & Plug","Bareshare"];
categories["Fiction"] = ["Flot","Independent"];
var nLists = 3; // number of select lists in the set

function fillSelect(currCat,currList){
var step = Number(currList.name.replace(/\D/g,""));
for (i=step; i<nLists+1; i++) {
document.forms['tripleplay']['List'+i].length = 1;
document.forms['tripleplay']['List'+i].selectedIndex = 0;
}
var nCat = categories[currCat];
for (each in nCat) {
var nOption = document.createElement('option'); 
var nData = document.createTextNode(nCat[each]); 
nOption.setAttribute('value',nCat[each]); 
nOption.appendChild(nData); 
currList.appendChild(nOption); 
} 
}



function init() {
 fillSelect('startList',document.forms['tripleplay']['List1'])
}

navigator.appName == "Microsoft Internet Explorer" ? attachEvent('onload', init,     false) : addEventListener('load', init, false);
function MM_validateForm() { //v4.0
  if (document.getElementById){
    var i,p,q,nm,test,num,min,max,errors='',args=MM_validateForm.arguments;
    for (i=0; i<(args.length-2); i+=3) { test=args[i+2];     val=document.getElementById(args[i]);
      if (val) { nm=val.name; if ((val=val.value)!="") {
        if (test.indexOf('isEmail')!=-1) { p=val.indexOf('@');
          if (p<1 || p==(val.length-1)) errors+='- '+nm+' must contain an e-mail     address.\n';
        } else if (test!='R') { num = parseFloat(val);
          if (isNaN(val)) errors+='- '+nm+' must contain a number.\n';
          if (test.indexOf('inRange') != -1) { p=test.indexOf(':');
            min=test.substring(8,p); max=test.substring(p+1);
            if (num<min || max<num) errors+='- '+nm+' must contain a number between     '+min+' and '+max+'.\n';
      } } } else if (test.charAt(0) == 'R') errors += '- '+nm+' is required.\n'; }
     } if (errors) alert('The following error(s) occurred:\n'+errors);
    document.MM_returnValue = (errors == '');
} }
</script> 

</head>
 <body>

    <table width="60%"><form action="process.php" method="post"     enctype="multipart/form-data" name="tripleplay"     onsubmit="MM_validateForm('fullname','','R','area','','R','ownermobile','','RisNum','email'    ,'','RisEmail','otherdetail','','R');return document.MM_returnValue">
       <tr>
    <td width="44%">Full Name : </td>
    <td width="56%"><input size="25" type="text" name="fullname" id="fullname" /></td>
  </tr>
  <tr>
    <td valign="top">Rental Type:</td>


    <td>

    <select name='List1' id="List1"     onchange="fillSelect(this.value,this.form['List2'])">
<option selected>Make a Selection</option>
</select>
<br /><br />
<select name='List2' id="List2" onchange="fillSelect(this.value,this.form['List3'])">
  <option selected>Make a Selection</option>
</select><br /><br />
<select name='List3' id="List3" onchange="getValue(this.value,     this.form['List2'].value, 
this.form['List1'].value)">
  <option selected>Make a Selection</option>
</select>
 </td>
  </tr>
  <tr>
    <td>Area : </td>
    <td><input size="25" type="text" name="area" id="area" />
      sq.ft.</td>
  </tr>
  <tr>
    <td>Owner Mobile / Landline</td>
    <td><input size="25" type="text" name="ownermobile" id="ownermobile" /></td>
  </tr>
  <tr>
    <td><p>E-mail</p></td>
    <td><input size="25" type="text" name="email" id="email" /></td>
  </tr>
  <tr>
    <td valign="top">Pictures of Property</td>
    <td>

      <input type="file" name="image_one" id="image_one" />


        <input type="file" name="image_two" id="image_two" />


        <input type="file" name="image_three" id="image_three" />
    </td>
  </tr>


  <tr>
    <td valign="top">Other details you would like to share about your property:</td>
     <td><textarea size="25" name="otherdetail" id="otherdetail" cols="45" rows="5">    </textarea></td>
  </tr>
  <tr>
    <td>&nbsp;</td>
    <td><input type="submit" name="submit" id="submit" value="Submit" /></td>
  </tr>
</form>
</table>
</body>
</html>

そして私のフォーム処理ファイルはこのようになっています。

<?
if( $_POST )
{
  $con =     mysql_connect("","","");

  if (!$con)
  {
    die('Could not connect: ' . mysql_error());
  }

  mysql_select_db("vkrental", $con);

  $users_fullname = $_POST['fullname'];
  $users_area = $_POST['area'];
  $users_List1 = $_POST['List1'];
  $users_List2 = $_POST['List2'];
  $users_List3 = $_POST['List3'];
  $users_ownermobile = $_POST['ownermobile'];
  $users_email = $_POST['email'];
  $users_image_one = $_POST['image_one'];
  $users_image_two = $_POST['image_two'];
  $users_image_three = $_POST['image_three'];
  $users_otherdetail = $_POST['otherdetail'];


  $users_fullname = htmlspecialchars($users_fullname);
  $users_area = htmlspecialchars($users_area);
  $users_List1 = htmlspecialchars($users_List1);
  $users_List2 = htmlspecialchars($users_List2);
  $users_List3 = htmlspecialchars($users_List3);

  $users_ownermobile = htmlspecialchars($users_ownermobile);
  $users_email = htmlspecialchars($users_email);
  $users_image_one = htmlspecialchars($users_image_one);
  $users_image_two = htmlspecialchars($users_image_two);
  $users_image_three = htmlspecialchars($users_image_three);
  $users_otherdetail = htmlspecialchars($users_otherdetail);




  $query = "
   INSERT INTO `vkrental`.`Owner_detail` (

`fullname` ,
`area` ,
`List1` ,
`List2` ,
`List3` ,

 `ownermobile` ,
`email` ,
`image_one` ,
`image_two` ,
`image_three` ,
`otherdetail`
)
VALUES ( '$users_fullname',
    '$users_area', '$users_List1','$users_List2','$users_List3', '$users_ownermobile', '$users_email', '$users_image_one','$users_image_two','$users_image_three', '$users_otherdetail'
        );";

  mysql_query($query);

  echo "<h2>.</h2>";

  mysql_close($con);
}
 ?>

そしてmysqlテーブルはこのようになっています

CREATE TABLE `Owner_detail` (
  `id` int(10) NOT NULL auto_increment,
  `fullname` varchar(30) NOT NULL,
  `List1` varchar(20) NOT NULL,
  `List2` varchar(20) NOT NULL,
  `List3` varchar(20) NOT NULL,
  `area` varchar(30) NOT NULL,
  `ownermobile` varchar(20) NOT NULL,
  `email` varchar(20) NOT NULL,
  `image_one` blob NOT NULL,
  `image_two` blob NOT NULL,
   `image_three` blob NOT NULL,
  `otherdetail` varchar(300) NOT NULL,
  PRIMARY KEY  (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8 AUTO_INCREMENT=24 ;

私の問題は、1) mysql テーブルで画像が [BLOB - 0 B] を示していますが、この画像を phpmyadmin と Web ブラウザーで表示する必要がありますか? 2) phpmyadmin(localhost) では、カーソルが動いているときはいつでも下線が表示されますが、Web ホストでは表示されません。なぜこれ？

どんな助けでも素晴らしいです。
