Usually, we issue the following commands to get MySQL from PHP:

$dblink = mysqli_connect("localhost", $username, $password, $database);
$result = mysqli_query($dblink, $query); //in which $query is your SQL statement


To solve the “question mark” issue, try add the following two lines before mysqli_query:


$dblink = mysqli_connect("localhost", $username, $password, $database);
mysqli_query($dblink, "SET CHARACTER SET utf8");
mysqli_query($dblink, "SET NAMES 'utf8'");
$result = mysqli_query($dblink, $query);

Hope this help and happy programming.

Basically, there are two methods: by creating a button at each row, or provide a checkbox at each row, then only a “submit” button at the end of the DataList.

The following is a portion of the source code, or you can download a sample developed using C# on VS 2008 here:

-------------------------------------------------------

<asp:DataList ID="DataList2" runat="server" BorderStyle="Dashed" BorderWidth="1"
        Width="50%">
        <HeaderTemplate>
            Name
        </HeaderTemplate>
        <ItemTemplate>
            <asp:CheckBox ID="chkAdd" runat="server" />
            <asp:HiddenField ID="hidId" runat="server" Value='<%#  DataBinder.Eval(Container.DataItem,"Id") %>' />
            <%# DataBinder.Eval(Container.DataItem,"Name") %>
            ($<%# Convert.ToDecimal(DataBinder.Eval(Container.DataItem, "Price")).ToString("0.00") %>)
        </ItemTemplate>
    </asp:DataList>
    <asp:Button ID="btnAddToCart2" Text="Add To Cart" runat="server" CommandName="addtocart2"
        OnCommand="DataList2_ItemCommand" />
    <br />
    You are adding the following items ID:
    <asp:Label ID="lblCartItem" runat="server"></asp:Label>
-------------------------------------------------------
public void DataList2_ItemCommand(object source, System.Web.UI.WebControls.CommandEventArgs e)
    {
        string sId="";
        foreach (DataListItem dli in DataList2.Items)
        {
            CheckBox currChk = (CheckBox)dli.FindControl("chkAdd");
            if (currChk.Checked == true)
            {
                HiddenField currId = (HiddenField)dli.FindControl("hidId");
                sId += currId.Value + ", ";
            }
        }
        lblCartItem.Text = sId;
    }

After searching and developing for weeks, finally I came out with a Chinese lunar calendar and put it on the right panel. Hope it is functioning probably. With this calendar, I will know when is the next “first day” and mid of the month so that I WON’T eat vegetables on that day. MUAHAHA:twisted:

P/S: Lunar calendar also used to determine high tide period as well as moon phase. It is good for fishermen.

Googled around and finally found a solution. Apparently it has sometime to do with ini_set() and some codes in some files need to be modified. The expert also uploaded the modified files or you can download a copy here.

Another solution can be found here.

1. Download mysqli and mysql connector for PHP from http://dev.mysql.com/downloads/connector/php/

2. Extract both zip files and copy to C:\Program Files\PHP\extension (create “extension” folder if it’s not there). “extension” folder should contain “libmysql.dll”, “php_mysqli.dll”, and “php_mysql.dll”.

3. Open “php.ini” from C:\Program File\PHP.

4. Change extension_dir to extension_dir = “c:\program files\php\extension”

5. Ensure the following statements is in php.ini:

extension=php_mysql.dll
extension=php_mysqli.dll

6. Restart Apache.

7. Re-run Zen Cart installation wizard. Zen Cart should be installed without any error by now.

On codebehind page, add the following:

private void Page_Load(object sender, System.EventArgs e)
{
button1.Attributes.Add(“onclick”, “jsFunc()”);
}

in which “jsFunc” is the JavaScript function you define in aspx page. With this, whenever button1 is clicked, “jsFunc” is called at client side.

Because DataList is databound control which repeats its item template as many times as there are rows in the data source to it. Therefore contents of template are wrapped into DataList’s Items (one DataList item per row in data source) which is a naming container to its contents (to keep control ID naming scope unique with repeated controls)

You’d need to note that to locate a specific Label control, you’d first need to locate specific dataList item, and run FindControl to it (for example DataList1.Items(0).FindControl(“label2″) ), and considering the databound nature, you’d probably want to loop through all items in the DataList’s Items collection to get to the every Label control. instead of getting to one on specific row.

Iterating through all items in DataList

VB
For Each dli as DataListItem in DataList1.Items
Dim currLbl As Label=DirectCast(dli.FindControl(“label2″),Label)
‘…
Next

C#
foreach(DataListItem dli in DataList1.Items)
{
Label currLbl = (Label) dli.FindControl(“label2″);
//…
}

asp:Label id=”lblDate” runat=”server” value=’<%# Eval(myDr["DateAdded"]) >’

Assuming “DateAdded” is a date/time field in database, the above statement returns a date/time value from database.

Now, if you would like to show only date portion of it. You should define format string within Eval, such as:

<%# Eval(myDr["DateAdded"], {0:d}) >

As mentioned in help file, the Eval function is used to define one-way (read-only) binding. There is another method called Bind, which is two-ways. We used <%# %> as data-binding expression. Another expression frequently used is <%$ %>, in which I normally use it to get keyword value from web.config, such as <%$ ConnectionStrings:myConnString %>.

DECLARE @i int

WHILE(@i < 5)
BEGIN
– do whatever you want here –
SET @i = @i + 1
END

Remember to increment/decrement the counter. Else, you will ended up in infinite loop.
