hola:
tengo una lista con las ciudades de mi provincia, como hago para cuando no existe la ciudad de una persona pueda seleccionar la opcion "otra.." y me aparezca un textbox para poder poner el nombre de su ciudad el codigo que uso (no es mio) es este:
formulario:
Código HTML:
<tr>
<td align="left"><img src="images/bullete.gif" width="4" height="6" /> </td>
<td align="left" class="wfrm2"><strong>Select Country</strong></td>
<td width="731" align="left" valign="bottom"><label>
<select name="country" id="country" style="width:300px" onchange="districtstatus()">
<option value="">--SELECT COUNTRY--</option>
<?php $quyCountry="select * from country_name order by country_name asc";
$db_c = new DB();
$db_c->query( $quyCountry );
if( $db_c->numRows() > 0 ) {
while( $data_c = $db_c->fetchArray() ) { ?>
<option value="<?php echo $data_c['id'];?>"> <?php echo $data_c['country_name'];?></option>
<? }}?>
</select>
</label> </td>
</tr>
<?php $state = getState($_SESSION['uid']); ?>
<tr>
<td align="left"><img src="images/bullete.gif" width="4" height="6" /> </td>
<td align="left"><strong>Province/State</strong></td>
<td align="left" valign="bottom">
<div id="disstatus">
<select name="region" size="1" class="text_area1" id="region">
<option value="">--SELECT PROVINCE--</option>
</select>
</div>
</label> </td>
</tr>
<?php $city = getCity($_SESSION['uid']); ?>
<tr>
<td align="left"><img src="images/bullete.gif" width="4" height="6" /> </td>
<td align="left"><span class="wfrmbold">City</span></td>
<td align="left"><div id="city_id">
<select name="city" size="1" class="text_area1" id="city" >
<option value="">--SELECT CITY--</option>
</select>
</div></td>
</tr> archivo donde obtengo los select de cada opcion (estado, ciudad):
Código PHP:
function districtstatus($obj,$country)
{
$query_dist1="select * from state_name where country_id='$country' order by state_name";
$fire=mysql_query($query_dist1);
$num=mysql_num_rows($fire);
if($num > 0){
echo "<select name='region' class='a11gray' id='region' onchange='districtstatus1()' >\n";
echo "<option value=''>-SELECT STATE-</option>\n";
while($query_dist11=mysql_fetch_array($fire)){
echo "<option value='".$query_dist11['id']."'>".ucwords($query_dist11['state_name'])."</option>\n";
}}else{
/*original
echo "<select name='region' class='a11gray' id='region' style='width:125px'>\n";
echo "<option value=''>-STATE-</option>\n";
*/
echo '<input type="text" name="region" value="" class="a11gray" id="region" style="width:125px">';
}
}
function districtstatus1($obj,$region)
{
$query_dist2="select * from city_name where state_id='$region' order by city_name";
$fire2=mysql_query($query_dist2);
$num1=mysql_num_rows($fire2);
if($num1>0){
echo "<select name='city' class='a11gray' id='city' onchange='districtstatus2()' >\n";
echo "<option value=''>-SELECT CITY-</option>\n";
while($query_dist22=mysql_fetch_array($fire2)){
echo "<option value=".$query_dist22[id].">".$query_dist22[city_name]."</option>\n";
}}else{
/** original
echo "<select name='state' class='a11gray' id='state' style='width:250px'>\n";
echo "<option value=''>-CITY-</option>\n";
*/
echo '<input type="text" name="state" value="" class="a11gray" id="state" style="width:250px">';
}
}
